Accelerometers approved for more critical usage
Used to monitor machinery vibration, the recertified Sensonics PZS accelerometers can now also be used to monitor gas turbine sets as well as motors, pumps and power turbines.
Eddy current probe operates at high temperatures
Sensonics has developed the PRS05 Senturion Proximity Probe capable of operating at temperatures over 200degC, which are common in applications such as steam and gas turbines.
This means it is virtually immune to base strain effects and less sensitive to temperature transients.
The piezo-electric shear mode sensor with its integrated electronics is contained within an inner metal enclosure, which is electrically and thermally insulated from the outer stainless steel body.
This design prevents earth loops and eliminates electrical interference.
The PZS4 accelerometer operates as a two-wire current loop device using a 18 to 28 volts DC constant current source of 2 to 10 mA, allowing very long interconnecting cables to be used.
The dynamic range is up to 70g peak over a standard frequency range of 0.4Hz to 11kHz (better than 3dB).
It is housed in a stainless steel hermetically sealed case to IP66 / IP67 and accepts a vibration limit of 200g peak, 500g shock and operates over a temperature range of -30C to +140C.
Weighing just 150 gms, the sensor has a single point mechanical fixing and a side entry electrical cable or connector, with a choice of different types.
The new accelerometer is an ideal sensor for monitoring vibration levels in a predictive maintenance role on all types of rotating machinery such as motors, fans, conveyors, gearboxes, turbines, compressors, mixers, etc. Request a free brochure from Sensonics ...
