Part No : SE-TS-AVRO TG/ TM
The RPM test bench is a specially developed test bench with multiple capabilities. This test bench is used for servicing, rectification and recalibration of tachometer indicators and tacho generators of four different types of aircraft i.e., Avro, Canberra, Kiran MK-I, Kiran MK-II.
Avro ac : Generator engine speed Pl No.KGA 0409
Canberra ac : Tachometer generator KGA -0409
Kiran MK-1 ac : Tachometer generator Pet No:6A/3252, kga0701
Kiran MK-II ac : Tachometer generator Pl No: 122RV/SB
It consists of three sub-systems
RPM is displayed either numerically or as percentage values in aircraft indicators
Caters to variation of tachometer indicators used in same aircraft
Tacho generator CPU and Servo Motor are based on micro controlled driven DC Servo Motor with built in optical encoder and chopped digital control (PWM)
Tachometers CPU is micro processor based, solid state with no moving parts
