Jiangyin No. 3 Electronic Instrument Co., Ltd.
Type QBJ-3800 steam turbine monitoring protector for multiplex channel plug combined monitoring panel mounted instrument.The monitoring and protection device of steam turbine operation condition is an indispensable means of detection, the measured parameters is very important
The device has the following characteristics:
1, the channel content free combination.
2, the number of channels free combination.
3, single, double channel arbitrary choice.
Type QBJ-3800 protection monitoring instrument can include: axial displacement, differential expansion, eccentric, speed, synchronizer, starting valve, oil tank oil level motivation, thermal expansion, vibration, bearing cover, shaft vibration, temperature measurement channel and combination.The device adopts each channel independently regulated power supply, are not interference; independent alarm switch output (DC27V.1A), independent risk switching output (DC27V.1A); the alarm value, risk value can be set arbitrarily; constant pressure output 1 ~ 5V; constant current output 4 ~ 20mA, the device of high precision, temperature drift of small, stable performance
