Cheap Pressure Transmitter

Introduction

A Cheap Pressure Transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission.

It can convert physical pressure parameters such as gas and liquid sensed by the load cell sensor into standard electrical signals (such as 4~20mADC, etc.) to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement and indication. and process regulation.

There are two types of pressure transmitters: electric and pneumatic. The electric unified output signal is DC signal such as 0~10mA, 4~20mA or 1~5V. The pneumatic unified output signal is a gas pressure of 20-100Pa.

Working Principle

The electrical component of the Cheap Pressure Transmitter to feel the pressure is generally a resistance strain gauge, which is a sensitive device that converts the pressure on the measured component into an electrical signal.

The most widely used resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. There are two types of metal resistance strain gauges: filamentary strain gauges and metal foil strain gauges.

Usually, the strain gauge is tightly bonded to the matrix that generates mechanical strain through a special adhesive. When the stress of the matrix changes, the resistance strain gauge is also deformed together, so that the resistance value of the strain gauge changes, so that the strain gauge changes. The voltage across the resistor changes.

Technical Data
