How to connect pressure sensor, pressure transducer or pressure transmitter to industrial instrumentation or PLC? ①Pressure sensor 4-wire Millivolt-output ②Pressure transducers 3-wire Voltage-output ③Pressure transmitters 2 wire 4-20mA current-output

① Creep Recovery The change in no--load output occurring with time after removal of A load which had been applied for a specific period of time. Usually measured over a specific time period immediately following removal of rated load and expressed as a percent of rated output over a specific period of time. ② Deflection The change of length along the primary axis of the load cell between no--load and rated load conditions. ③ Drift A random change in output under constant load conditions.

Technical term for load cell（Part 1）① Ambient Conditions Humidity, pressure, temperature, etc. of the medium surrounding the load cell. ② Ambient TemperatureThe temperature of the medium surrounding the load cell. ③ Angular Load Eccentric A load applied eccentric with the primary axis at the point of application and at some angle with respect to the primary axis.

Potemtionmeter displacement sensor is a new type of distance sensor developed by principle using linear sensor. It consists of a potentiometer, a control circuit and a group of mechanical components. It can accurately measure position of the moving object, displacement and other changes. The potemtionmeter displacement sensor can measure displacement, length, vibration and distance. It has high linear accuracy.

How to select the appropriate sensor When we provide sensing solutions, it is very important to choose the right products. There are so many kinds of sensors. Once the selection is not good, it will bring a lot of issues to the application.

Principle of magnetostrictive linear displacement sensor The magnetostrictive linear displacement (liquid level) transmitter is mainly composed of a measuring rod, an electronic silo and a non-contact magnetic ring (floating ball) on the measuring rod. The measuring rod is equipped with magnetostriction wire (waveguide wire).

Absolute pressure sensor: absolute pressure means the total pressure on the surface area of an object. Its zero point is based on absolute vacuum, we can call it total pressure. Gauge pressure sensor: Gauge pressure= total pressure- one atmospheric pressure. Its zero point is the local atmospheric pressure as the reference point. The difference between them only the zero point.

Piezoresistor pressure sensor is a sensor made of piezoresistor effect of monocrystalline silicon and integrated circuit technology. When the monocrystalline silicon material is affected by the force, the resistivity changes, through measuring circuit, ratiometric output signal to force change can be obtained.

Temperature Sensor RTD Resistance temperature sensor is usually made from high purity platinum metal. Their resistance has a direct and repeatable relationship with temperature.RTD platinum temperature sensor has long term stability and strict tolerances over a wide temperature range.
