0.5-4.5V I2C Pt1000 Temperature Pressure Liquid Vapors Sensor Transducer
Product DiscriptionWNK81TP series temperature and pressure sensor is composed of high precision silicon pressure sensor and PT100 temperature sensor.
A high-precision PT100 temperature sensor is embedded in the pressure sensor's stainless steelhousing base, and a thermally conductive glue is potted in the gap.It will greatly reduce the hysteresis of
temperature conduction when the PT100 sensor is not in contact with the measurement medium.
WNK81TP is committed to providing new measurement methods, saving material costs of sensors,
and convenient for customers.
