Product Overview
The Kongsberg Maritime Autronica GC-110 is a compact, rail-mounted temperature transmitter for marine and industrial monitoring systems.
It receives resistance signals from Pt100 or Pt1000 temperature sensors, linearises the measurement and converts it into a standard 4–20 mA output. Its terminal-block construction permits multiple transmitters to be mounted side by side inside control or monitoring cabinets.

Key Features
- Compatible with Pt100 and Pt1000 sensors
- Standard 4–20 mA control-system output
- Two-wire power and signal arrangement
- Four-wire sensor input minimises cable-resistance error
- Compact terminal-block enclosure
- Direct mounting on TS-32 or TS-35 rails
- Multiple units can be mounted side by side
- Transient-protected power and output wiring
- Sensor-break fault indication
- Pre-adjusted factory measuring ranges
- Suitable for intrinsically safe applications with a DZ-110 barrier
Sensor-Fault Indication
If one or more sensor wires become open circuit, the transmitter output changes to:
- Below 3.6 mA; or
- Between 25 and 33 mA, depending on configuration.
This allows the vessel’s alarm and monitoring system to distinguish a faulty sensor circuit from a normal temperature measurement.
Typical Applications
- Main and auxiliary engine temperature monitoring
- Exhaust-gas and cooling-water systems
- Fuel-oil and lubricating-oil systems
- Bearings, pumps and electric motors
- Cargo and service-tank temperature monitoring
- Boilers and heat exchangers
- Refrigeration machinery
- Alarm monitoring and automation cabinets
- Offshore platforms and FPSOs
