TEK-BAR 3110A Differential Pressure Transmitter

1. Mô tả TEK-BAR 3110A | Đồng hồ chênh áp TEK-BAR 3110A

The Tek-Bar 3110A Explosion-Proof Differential Pressure Transmitter have excellent stability, high accuracy, and include features that facilitate easy installation, start up, and minimum maintenance thereby lowering process downtime and overall cost of ownership in the long run. These transmitters are equipped with an automatic temperature compensation function integrated into its advanced signal processing circuitry to ensure high reliability and performance corresponding to change of ambient temperature.

2. Nguyên lý hoạt động TEK-BAR 3110A Differential Pressure Transmitter

The Tek-Bar 3110A Explosion-Proof Differential Pressure Transmitter uses Capacitance pressure sensors. It consists of two metal plates that are separated by sensing diaphragm. An electrically insulating fill fluid (silicon oil), transfers the movement from isolating diaphragm to the sensing diaphragm. The capacitance characteristics of the sensing element changes. These signal transfer to the electronic circuitry of transmitter that converts the change in capacitance to the output signal. Capacitance transmitters are configured for differential pressure measurement. Usual outputs are voltage or current.
