Description

SMC18B series pressure transmitters chose dry ceramic piezoresistancepressure sensor sensechip with high precision and stabilityand integrate digital adjusting chip to make digitalcompensation for sensor’s drifting, sensitivity and temperature drift, andconvert tested medium’s pressure to standard electric signal. Highquality sensor chip, masterful encapsulation technique and maturedand perfect assembly art assure the product’s high quality and good performance.The product provides various treaded coupling and lead methods so that we canmeet customers’ request to the highest extent.

Meanwhile we company can provide standard module without encapsulation which has sameelectric property with the finished product.

 Characters

High integration level,small volume, High precision, good stability,

Fast response speed, lowpower consumption, good consistency

Strong resistanceability to overload shock and disturbance overvoltage and overcurrentprotection

Temperature compensationfor whole temperature scope

Application of products

Thisproduct is widely used in many fields such asautomobiles, center air condition and refrigerating equipments, water treatment projects, buildings water supply, industrial processcheck and control, hydraulic and pneumatic control projects.
