Metallic Capacitive Sensor

Metallic Capacitive Sensor 3

Capacitive sensor is a passive transducer, which converts the non-electric physical quantity into corresponding capacitance. The capacitance is changed to a voltage or current signal, and is then amplified and processed. Capacitance sensor features stable temperature, simple structure, good dynamic response and non-contact measurements. Metallic capacitance sensor is utilized where small distance or displacement is to be measured and higher resolution is required.

Circuit board A

EST4300-A circuit board, available for small capacitance sensor, transmits differential capacitance signals to two-wire 4–20 mA with stable and reliable performance. Compatible with ROSEMOUNT’s 275/375 communication interface and conforming to the HART protocol, EST4300-A can perform temperature compensation at two pressure points and three temperature points.

Circuit board B

EST4300-B circuit board, available for small capacitance sensor, is the upgrade of EST4300-A. With the sensor circuitry completely isolated from the housing and the feed thru-capacitor bypass technology, EST 4300-B can effectively avoid the effects of external high-voltage signal or interference to the measurements, and perform multi drop temperature compensation.

HART475 Field Communicator

HART 388 field communicator enabling commissioning, setup and other operations to HART-compliant smart instruments. Both Chinese and English menu guaranteeing easier operation.
