Product Introduction

Functional Features
Dual channel design: It can simultaneously connect two independent electric speed sensor signals to monitor the vibration of two bearings, output two independent signals proportional to the peak vibration speed or displacement, or output one signal proportional to the maximum vibration speed or peak value of the two input signals.
Self check function: Equipped with a built-in "self check" circuit, it can continuously monitor sensor and transmitter circuit faults. If a fault is detected, the logic "OK" output will change state, and the current output will change from 4-20mA to 0mA.
Compliant with universal standards: Compliant with the most universal standards such as VDI2056, ensuring its compatibility and interchangeability in different application scenarios.
Flexible configuration: Initial settings can be completed through toggle switches and rotary switches, and the factory settings are the most commonly used working mode, which can also be customized according to user requirements.

technical parameter
Sensor input: can be connected to two independent electric speed sensors, such as EPRO's PR9266/... and PR9268/... series; The maximum allowable input voltage is ± 10V, and the input impedance is>100K Ω.
Measurement range: The vibration velocity range can be selected from 0... 5/10/25/50/100mm/s by toggling the switch, depending on the input sensitivity of 30/28.5/22mV/mm/s; The amplitude (0-P) range can be selected from 0... 25/50/100/125/250/500 μ m, with a sensitivity of 30/28.5/22mV/mm/s.
Frequency range: High pass filter is 5/10/15Hz, low-pass filter is 50-1500Hz.
Linear error:< 0.25%.
Temperature drift: Zero point<0.05%/K, gain range<0.01%/K.
Time drift: Zero point<0.01%/24 hours, gain range<0.01%/24 hours.
Measurement signal output: Two 0/4... 20mA current outputs, one for each channel, proportional to the corresponding input, or one current output proportional to max (Sxpp, Sypp), Smax, allowing a load of 500 Ω; Two buffered voltage outputs (2-10V), one for each channel, proportional to the input dynamic signal; One "OK" status output and two limit value outputs.
Power supply: 18... 24... 31.2V DC, the transmitter circuit is electrically isolated from the power supply through a DC/DC converter.
Current consumption: approximately 100mA/24V.
Power consumption: approximately 2.5 watts.
