Output tests can also be run at the sensors by attaching the voltage meter at the sensor output and watching as the sensor is extended or raised. Voltage skips or gaps can be detected using this technique. GREER COMPANY 1918 E. Glenwood Place, Santa Ana, CA 92705 Tel: (714) 259-9702 Fax: (714) 259-7626 ®... -
Page 7: Testing Pressure Transducers Through Drive Voltage
Refer to the procedure on the following page for testing the resistance of a normal transducer. Remember that the readings must balance. If not, the transducer is unbalanced and may give faulty load readings. GREER COMPANY 1918 E. Glenwood Place, Santa Ana, CA 92705 Tel: (714) 259-9702 Fax: (714) 259-7626 ®... -
