Seismic Vibration Transmitters

The TR1101 seismic vibration transmitter is a cost-effective solution for monitoring case vibration on balance of plant machines. The TR1101 conditions the signal from an accelerometer or velocity transducer and provides a 4-20 mA output in acceleration, velocity or displacement. Features: measures machinery case vibration; 4-20 mA output in acceleration, velocity or displacement; buffered output up to 300 metres (1,000 feet); compatible with other manufacturers’ sensors (accelerometer or velocity sensor); aluminium cast (copper free) case with epoxy potting for better environmental protection and reliability; and compact size. Specifications: electrical power supply – 22-30 V DC, 100 mA (non-isolated); frequency response (±3dB) acceleration – 2.0 – 10 kHz; velocity – 2-10 kHz (velocity sensor); velocity – 10-5 kHz (accelerometer); displacement – 10-3 kHz (velocity sensor); acceleration (low frequency) – 1.0-100 Hz; velocity (low frequency) – 1.0-100 Hz (TM079VD); and displacement (low frequency) – 1.0-100 Hz
