Speed Indicators

Pantech's RPM Indicator cum Controller, model 857 is an ideal instrument for measuring the speed of any rotating part. The input signal can be pulses from any PULSE generating device . The basic feed in parameter for RPM calculation and display is PPR ( Pulse per Revolution Ratio ). Based on these feed ins, the instrument comes up with a definite display for SPEED. Model 857 is capable to display the RPM value to the resolution of maximum 44.5 digits with programmable range selection. However the RPM value is auto calculated, but this programmed range can set the value of retransmission signals which can be optionally taken from the instrument. Further it can be designed to generate maximum of 4 nos. of potential free contacts. All the configurations like : PPR, setpoints, alarm types, ZERO and SPAN for retransmission etc. can be done with the help of front keys only . It is also facilitated with internal transmitter power supply of 1224 V DC, to power up proximity sensors.
