Hazardous area accelerometers

IMI developed the new sensors for gas turbine monitoring, commissioning of nuclear power plants and machinery monitoring in high temperature environments.

Model EX615A42 is designed for use in environments to 260°C and offers sensitivity of 100pC/g, a measurement range of ±200g peak and a frequency range of 5kHz ±5%. The sensor has a stainless steel housing and features a 3m armoured, low-noise PTFE cable terminating in pigtails.

Model EX619A11 is capable of operation to 482°C with sensitivity of 50pC/g, measurement range of ±500g and frequency range of 3kHz ±5%. This sensor has a nickel housing with an integral 2.1m MI hardline cable terminating in a 2-pin MIL-C-5015 connector.

Additional characteristics include ATEX approval, high shock survivability, high resolution and large dynamic range option. PCB Piezotronics also offers several differential charge amplifiers to support the two new sensors that convert the high impedance output to a low impedance voltage signal for transmission and data collection. When paired with charge accelerometers, these charge amplifiers convert the sensor output into a single-ended output (measurement output as a signal and ground).
