EZQ Pressure Sensor

EQZ Pressure sensor

EQZ is a SENTRY platform compatible pressure sensor used to measure pressures of various mediums – specifically gasses and liquids. Sensor is attached to the pipes or tanks using threaded connection. The enclosure is made from stainless steel. Sensor is designed to measure pressure as a primary measurement metric and temperature as a secondary metric. The temperature is used for pressure reading temperature compensation, however can be read as a secondary indicative measurement.
