ZA3502 Three-wire Rotating Velocity /Key phase Transducer

ZA3502 is single-channel rotating velocity transducer. It is mainly used in realtime measuring rotating velocity of rotating machinery. Value of rotating velocity within 4～20mA can be output. Low frequency option of ZA3502 can measure the zero rotating velocity of steam turbine. High integrity , no need for proximitor and high reliability

Key words:

Eddy current displacement sensor, vibration speed sensor, related test instrument

Product Classification:

Three-wire Transducer

ZA3502 Three-wire Rotating Velocity /Key phase Transducer

High integrity , no need for proximitor and high reliability

ZA3502 integrate the function of proximitor and transducer . So for ZA3502, it only need probe and extension cable. Because of this reason, parts for monitor become less and greatly enhance the reliability .

Easy installation, No need for adjustment

ZA3502 is suitable for rotating velocity monitor of rotating machinery. Installation of ZA3502 is very easy. Just put it where the proximitor locates.

Measurement point of machine: a groove is required to carve in the rotating axis with depth over 1mm. Probes is fixed in the groove and then connect the probe to ZA502 monitor.

Parameters of ZA3502 have been adjusted and calibrated before delivery. Generally you need not to adjust or calibrate again but connect cables. Detailed info please see the user manual.

Standard key phasor TTL output

Buffered output standard TTL electrical level can be sent to status monitor as key phase signal Standard signal input to PLC or DCS to be processed as rotating velocity signal.

ZA3502 can be connected to all our 8mm eddy current sensors.
