Summary

SMC18B series pressure transmitters chose dry ceramic piezoresistivepressure sensor sense chip 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 qualityand good performance. The product provides various treaded couplingand lead methods so that we can meet customers’ request to the highest extent.

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

Characters
