TM41 - Turbine Governor Temperature Spread Monitor

Affordable alternative to full control system retrofit
Easy to install - Increased reliability - Programmable and configurable

 

The TM41 microprocessor system is designed to meet the requirements of Gas Turbine GOVERNING and TEMPERATURE SPREAD MONITORING.

The processor, I/O modules, ¼ VGA screen and keypad are housed in a 3U high 19" rack subassembly.
A wide range of input and output modules provides interface with plant devices and options for alternative or additional functionality.
Obsolete and unreliable equipment is replaced with modern digital electronics having high reliability and accuracy and is an affordable alternative to a full control system retrofit.
Communication facilities provide interface with other diagnostic and control equipment.

Temperature Spread Monitor

The TM41 is programmed to perform temperature spread monitoring functions in accordance with engine manufacturer's specification.

Typical Functionality

  • Signal validation - discount faulty inputs and alarm
  • Calculate average of healthy thermocouples
  • Calculate deviation of individual from average
  • Alarm on deviation exceeding alarm setpoint
  • Trip on deviation exceeding trip set point or number of failed thermocouple inputs exceeds set point

TM41 - Turbine Governor Temperature Spread Monitor

Governor

The TM41 can be fitted with pin compatible multiway connectors to mate directly with an existing governor (typically Woodward 43027) and therefore directly interchangeable.

TM41 - Turbine Governor Temperature Spread Monitor

The TM41 will interface with the retained or replacement fuel system,sequence and unit control devices.

Typical functions

  • Power Turbine Speed Control
  • Gas Generator Speed limit
  • Gas Generator Exhaust Temperature Control
  • Gas Generator Compressor Discharge Pressure Limit Control
  • Acceleration and deceleration schedules
  • Light off to Idle Control
  • Idle to Minimum Governor Speed Control
