What are the product features of PT100 temperature sensor?

The transmitter of PT100 temperature sensor usually consists of two parts: sensor and signal converter. Sensors are mainly thermocouples or thermal resistances; signal converters are mainly composed of measuring units, signal processing and conversion units (because industrial thermal resistances and thermocouple scales are standardized, signal converters are also called as independent products. Transmitter), some transmitters add display unit, and some also have fieldbus function.

Product features of PT100 temperature sensor

1. The PT100 temperature sensor is packaged in a stainless steel sleeve for durability

2. The movable screw of PT100 temperature sensor is easy to use

3. PT100 temperature sensor is manufactured in accordance with the international IEC 751 international standard, plug and play

4. Various probe sizes of PT100 temperature sensor can be selected for a wide range of applications

5. PT100 temperature sensor has the advantages of high precision, high stability and high sensitivity

6. PT100 temperature sensor is compact and economical.

Are there other types of PT100 temperature sensor?

PT100 temperature sensor does not exclude other standardized output signals with special provisions. The temperature transmitter can be divided into two-wire system and four-wire system according to the power supply wiring mode. Transmitter has electric unit combination instrument series (DDZ-Ⅱ type, DDZ-Ⅲ type and DDZ-S type) and miniaturized modular type, multi-functional intelligent type. The former does not have PT100 temperature sensor, and the latter two types of transmitters can be easily combined with thermocouples or thermal resistances to form transmitters with sensors.

How to use PT100 temperature sensor correctly?

The PT100 temperature sensor is an analog signal. It has two forms in practical applications: one is to collect the PLC that does not need to be displayed. In this case, only one integrated circuit of the PT100 temperature sensor is required. Pay attention It is this integrated circuit that collects not the current signal but the resistance value. The integrated circuit of the PT100 temperature sensor (which requires a +-12VDC power supply to provide the working voltage) directly changes the collected resistance into 1-5VDC and inputs it to the plc. After a simple +- */ The corresponding temperature value can be obtained by calculation (this form can collect multiple channels at the same time), and there is a separate PT100 temperature sensor (working power supply is 24VDC), which generates a 4-20MA current, and then passes a The 4-20MA current circuit board changes the current of 4-20MA into a voltage of 1-5V. The difference is that an electromagnetic indicator can be connected. The other basics are basically the same and will not be explained in detail.
