How accurate is a RTD sensor (Pt100) classes A, B In China's national standard, PT100 has two accuracy classes: Class A and class B Measuring Range：-200℃～+850℃Class A accuracy（0.15+0.002*|t|）℃；Class B accuracy（0.30+0.005*|t|）℃； Note: |t| is the absolute value of actual temperature.

A temperature transmitter is a device that connects to a temperature sensor to transmit the signal elsewhere for monitoring and control purposes. Typically, the temperature sensor is either an RTD(PT100 or PT1000), thermistor or thermocouple type sensor and will interface with a PLC, DCS, data logger or display hardware. The temperature transmitter's role is to isolate the temperature signal, filter any EMC noise, amplify and convert the temperature sensor's signal to a 4-20mA or 0-10V DC range for further use.

Classified by the force direction, load cells can be divided into the following types: ① Tension ② Compression ③ Alternating ④ Bending

Piezoresistive pressure sensor diffusion silicon pressure sensor The piezoresistive sensor has become a commonly used pressure sensor thanks to the widespread use of MEMS manufacturing technologies. These make the sensors relatively inexpensive to produce, assuming they do not need specialized packaging to handle dirty or hostile environments.

Physical separation from hazardous media: Fluid-isolation barrier can be implemented to prevent corrosive media coming into direct contact with the sensor diaphragm; Heat is dissipated from the media in the tube.

Pressure sensors for corrosive liquids and gasesPressure sensors for use with corrosive media often feature housings made from stainless steel or plastics such as PVDF, PVC or PPS. The sensor elements themselves are typically ceramic.However, ORR Sensor use a stainless steel diaphragm backed by silicon oil that transfers pressure to the sensing element.

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.
