Piezoelectric Active Sensors of Grain Loss DPZPA

They are intended for mechanical energy conversion of grain fall on the sensor working surface to a square-shape electric signal. 

 

DPZPA sensors operate together with an on-board computer or monitor unit mounted on combine harvesters to control losses of grain after straw shaking and cleaning.

There are two types of sensors: square DPZPA-P sensors and tubular DPZPA-T sensors.

Sensor protection level: IP 55 level sealing protection according to GOST 14254-96.
