PCH 1275 and 1277 ATEX Vibration Sensors

PCH 1275 and 1277 ATEX Vibration Sensors

PCH 1275 and 1277 ATEX Vibration Sensors

Do you need to monitor critical rotating machinery in ATEX zones?

The PCH 1275 and 1277 Compact Vibration Guards are Ex certified and approved for mines and other hazardous areas. The compact PCH 1275 and PCH 1277 monitors with internal vibration sensors are ideal as part of the safety chain for dangerous machinery where high accuracy and fast response times are vital.

PCH 1275 and PCH 1277 comply with Functional Safety (EN13849), PL-d (SIL 2).The PCH 1275 and PCH 1277 vibration guards consist of a vibration sensor as well as circuitry for conditioning, alarms and output, all embedded in a stainless steel housing. 

The ATEX certified vibration sensors compare the actual vibration levels with the internal thresholds 10 times per second. They can give you early warning of machine faults or even trigger an emergency shutdown of your machinery.

PCH 1275 and PCH 1277 are suitable for ATEX zones 1 and 21.

Measurement range, alarm limits and delay times can be adjusted directly in the PCH 1275 or 1277 vibration guard according to the machine type and size it is to monitor. With the PCH 1277 vibration sensor, you can also change all settings using the complementary PCH user software, including readouts of vibration level, status and offline FFT analysis up to 1000 Hz.

Standard ISO 10816-3/20816-3 (2/10-1000 Hz) or customized filter ranges like 1-3/300 Hz is also available.

The PCH 1275/1277 vibration sensors monitor seismic mechanical vibrations according to DIN/ISO 10816/20816 as default.

The compact ATEX vibration sensor series is available in two types: to measure velocity (mm/s) or acceleration (m/s2). Low frequency versions are available. Individual measuring parameters can be customized.PCH 1275 and 1277 comply with Functional Safety (EN13849), PL-d (SIL 2).
