Products for Ruston TA ( TA-1260 , TA-1500 , TA-1750 ) and Ruston TB (TB-3000 , TB-4000 , TB-5000 , TB-5400 ) Ruston Gas Turbines.

In the last 30 years PSI has developed numerous products to solve customers problems. Current examples are PLC Temperature Monitors and Annunciators, ignition systems, speed probes, thermocouples and wrap around exhaust joints that eliminate the need to disassemble the exhaust stack in future maintenance routines.


The PS-4010E/xx duplex thermocouple is a fit, form, and function replacement for the OEM original on TA and TB series turbines. This is a Type K thermocouple accurate to +/- 2 deg. F at Tmax. The duplex thermocouple is actually two thermocouples in one allowing dual monitoring functions, redundancy setup or the ability to changeover connections in the event one side fails.

The PSI / Chentronics retrofit ignition system is an exact fit replacement for the existing Ruston exciter and igniter. It has been designed to eliminate the unreliable operation of the old system that occurs when (1) moisture condensation on the ignitor prevented it from firing, (2) Low LCV gas for ignition is difficult to ignite.

The new system consists of 24 VDC exciter unit, which fits in the same place and utilize the same mounting holes as the old transformer. A shielded cable connects the exciter to the igniter plug and the plug. The igniter plug utilizes an adapter to allow installation on the turbine without further modification.
