Description
Damcos MAS 2600/2P
Product Overview
The Damcos MAS 2600/2P is a legacy amplifier assembly used within the Damcos MAS 2600 marine tank-level measurement system. Its job is to process the electrical signal from the associated MAS 2600 pressure transducer and provide the conditioned measurement used by the vessel’s tank-gauging system. This distinction matters during procurement: the MAS 2600/2P is an amplifier board, not the submerged pressure sensor itself and not a complete tank transmitter. Current cross-reference records identify 165B9160 as the replacement for the obsolete 2600/2P amplifier.
Within the Damcos MAS 2600 architecture, the amplifier is one part of a larger measurement chain consisting of the pressure transducer, interconnecting wiring, amplifier, and vessel monitoring or automation interface. MAS 2600 systems are used for marine tank-level and tank-contents measurement, including ballast and service-tank applications. Existing system records show numerous MAS 2600 configurations with different pressure ranges, cable lengths, and transmitter arrangements, so the amplifier should be matched to the installed transducer and system configuration rather than selected only by physical appearance.
For a legacy vessel, MAS 2600/2P is primarily a maintenance and replacement item. The important procurement question is whether the replacement amplifier preserves the original measurement chain and calibration. A catalog reference to 165B9160 establishes a replacement relationship, but it should not by itself be treated as proof that every historical MAS 2600 installation can be converted without checking the transducer, range, wiring, and calibration settings. One current listing describes 165B9160 as a MAS2600 amplifier with eight ranges and mounting hardware.
Product Introduction
When a marine tank-gauging channel fails, replacing the complete pressure transmitter is often unnecessary. The MAS 2600/2P addresses the electronics side of the measurement chain, allowing maintenance teams to replace the legacy amplifier while retaining the installed transducer when compatibility has been confirmed.
The practical catch is calibration. The amplifier is not simply a generic analog signal converter; its relationship with the MAS 2600 transducer and selected measurement range determines what the vessel’s monitoring system sees.

Specification note: Public records confirm the amplifier identity and replacement relationship, but they do not provide a sufficiently authoritative standalone electrical specification for every parameter above. The complete MAS 2600 system has configuration-dependent pressure ranges and output characteristics, so those values should not be transferred blindly to the 2600/2P board.

Major Features / Practical Advantages
MAS 2600 System Compatibility
The main value of the MAS 2600/2P is its role within an established Damcos tank-gauging architecture. It is intended to work with the associated MAS 2600 transducer and amplifier arrangement rather than serving as a universal pressure-transmitter PCB.
This is particularly relevant on older vessels where the installed tank sensors and wiring remain serviceable but the amplifier electronics have become unavailable.
Obsolete Part With a Documented Replacement
The 2600/2P is listed as obsolete, with 165B9160 identified as its replacement. Several independent Damcos parts catalogs repeat this cross-reference.
That is useful for procurement, but there is an important engineering distinction: replacement reference does not automatically mean zero-configuration replacement. The existing MAS 2600 transducer and its measurement range still need to be identified.
Supports the 4–20 mA Measurement Architecture
The MAS 2600 family uses a conventional 4–20 mA signal path for integration with marine automation and tank-monitoring equipment. A current MAS 2600 specification record describes the system as a two-wire 4–20 mA transmitter architecture.
This allows the processed measurement to be presented to the vessel’s monitoring or automation system without requiring a proprietary high-speed digital network.
Eight-Range Replacement Reference
The documented replacement 165B9160 is described in current parts records as a MAS2600 amplifier with eight ranges and mounting. That makes the replacement reference particularly relevant when rebuilding older MAS 2600 installations.
Do not, however, assume that “eight ranges” identifies the exact range configured on the customer’s original installation. The vessel’s tank depth and transducer configuration still determine the correct calibration.
Marine Tank Gauging Applications
The MAS 2600 family appears in vessel records for ballast tanks, tank-level sensors, tank contents measurement, and related marine gauging systems. Current Damcos service records continue to show MAS2600 installations across vessels in Singapore and other marine environments.
Useful for Legacy Replacement Work
For an older vessel, retaining the original transducer can be valuable when its mechanical installation is difficult to access. Replacing the amplifier electronics may avoid disturbing the tank-mounted sensor, provided the original transducer remains within specification and is compatible with the replacement amplifier.
That is a maintenance decision, not a guaranteed drop-in conversion.

FAQ
What is the Damcos MAS 2600/2P?
It is a transducer amplifier board used in the Damcos MAS 2600 marine tank-level measurement system. It is not the pressure transducer itself. Current parts records identify the obsolete 2600/2P as replaced by 165B9160.
Is MAS 2600/2P a complete level transmitter?
No. It is the amplifier portion of the MAS 2600 measurement chain. The complete installation also involves the pressure transducer, wiring, mounting arrangement, and the vessel’s tank-monitoring interface.
Is 165B9160 a replacement for MAS 2600/2P?
Yes. Multiple current Damcos parts listings identify 165B9160 as the replacement for the obsolete 2600/2P amplifier.
Can I hot-swap the MAS 2600/2P?
Do not assume hot-swapping is supported. This is legacy marine measurement electronics, and the published replacement records do not establish a hot-swap procedure. Isolate the electrical loop before removing the amplifier and follow the vessel’s electrical safety procedure.
Does MAS 2600/2P support firmware v3.1?
No reliable public documentation was found establishing a firmware version such as v3.1 for this specific amplifier board. Firmware information from another MAS 2600 generation should not be transferred to the 2600/2P.
Can I use any MAS 2600 pressure transducer with it?
No. The transducer must match the amplifier’s supported electrical and measurement configuration. MAS 2600 installations use different transducer ranges and configurations. A replacement should therefore be checked against the original transducer marking and tank calibration.
Is MAS 2600/2P suitable for PLC or DCS applications?
Indirectly. The board belongs to the MAS 2600 marine tank-gauging system, whose measurement architecture provides a conventional 4–20 mA signal to the vessel monitoring or automation system. It should not be treated as a standalone PLC analog-input module.
What should I verify before buying a replacement?
Verify the original MAS 2600 configuration, pressure-transducer model, measurement range, amplifier identification, wiring, calibration range, and vessel automation interface. If replacing 2600/2P with 165B9160, retain the original configuration information so the new amplifier can be commissioned against the same tank measurement.
Procurement Note
For Damcos MAS 2600/2P, the most important fact is that it is an obsolete amplifier board, not a complete transmitter. The documented replacement is 165B9160.
Before approving the replacement, obtain:
- Original MAS 2600 amplifier part number.
- Pressure-transducer model and nameplate data.
- Tank measurement/calibration range.
- Existing 4–20 mA scaling.
- Wiring and connector arrangement.
- Any vessel-specific calibration records.
- Replacement board identification and revision.
- Evidence of electrical and output testing.
For New Surplus inventory, verify the actual board marking and revision rather than relying solely on a catalog description. For Used or Refurbished equipment, a power-up test alone is not sufficient; the amplifier should be checked against an appropriate simulated transducer input and its 4–20 mA output verified across the relevant measurement range.
Do not substitute 165B9160 solely because the board looks similar. The documented replacement relationship is useful, but commissioning still needs to preserve the original MAS 2600 measurement range and tank calibration.
