BJKERE VRT-2/T VRT-2T VRT-2(T) type vibration velocity tansmitter and temperature transmitter
VRT-2T is a small integrated, independent two-wire, probe type transmitter. Its two 4-20mA output signals are directly proportional to the true effective value (intensity) of the vibration velocity of the measured object and the temperature change at the measurement point.
This transmitter is easy to install and cost-effective, making it very suitable for online measurement of vibration safety and temperature rise safety for various large and medium-sized rotating machinery and moving equipment (such as fans, water pumps, reducers, bearing seats, rolling friction bodies, etc.).
This transmitter can be directly used with the KR-32 dual channel equipment safety monitor produced by KeRe Company, and can also be easily connected to computer measurement and control systems such as DCS and PLC.
