AMAT 0190-25588 Pressure Sensor

AMAT 0190-09484 Temperature Controller Module

Product Details Introduction

A pressure sensor is a device that can measure pressure and provide electrical signals. They are widely used for automation and control purposes in industrial production. There are different types of pressure sensors to choose from, including strain sensors, resistance sensors, capacitance sensors, piezoelectric sensors and Hall effect sensor. Each type has its own working principle and characteristics.

Here are some key points to consider when understanding pressure sensors:

Classification of pressure sensors:

Strain based pressure sensors: These sensors use strain gauges to measure deformation caused by pressure.

Resistance pressure sensors: These sensors use changes in resistance to measure pressure.

Capacitive pressure sensors: These sensors use changes in capacitance to measure pressure.

Piezoelectric pressure sensors: These sensors use the Piezoelectricity to measure pressure.

Hall effect pressure sensors: These sensors use the Hall effect to measure pressure.

Other types include optical, fiber optic, and ultrasonic pressure sensors.

Working principle of resistive pressure sensor:

Resistance pressure sensors (such as strain gauges) rely on changes in resistance to measure pressure.

They are usually connected to the Wheatstone Bridge circuit for accurate measurement.

When pressure is applied, the resistance of the sensor changes, causing the Bridge circuit to be unbalanced.

The output voltage of the Bridge circuit is proportional to the applied pressure.

Application of pressure sensors:

Pressure sensors have various applications, including compressors, air conditioning systems, and refrigeration equipment.

They are used to monitor and control the pressure in these systems.

The pressure sensors used in these applications are usually compact in size and easy to install

Remote monitoring and control: The temperature controller module usually supports remote monitoring and control, and can be remotely operated and parameter adjusted through a network connection.
