The SWB series integrated temperature transmitter temperature measuring instrument can be widely used in industrial sectors such as metallurgy, petroleum, chemical, power, light industry, textile, food, national defense, and scientific research.
The SWB series integrated temperature transmitter consists of a temperature measuring probe (thermocouple or thermal resistance) and a two-wire solid-state electronic unit. The solid-state module is directly installed in the junction box of the temperature measuring probe, forming an integrated temperature transmitter. There are the following advantages:
1. The integrated structure is easy to install and saves lead wires.
2. Large output signal, strong anti-interference ability, linear correspondence with temperature, and simple display instrument.
3. Solid module earthquake and moisture resistance, reverse connection protection, and current limiting protection ensure high operational reliability.
4. Output a unified 4-20mA signal, which can be used in conjunction with microcomputer system DDZ-III S-type instruments or other conventional instruments.
5. Solid state modules are manufactured according to intrinsic safety and explosion-proof standards, and can be made into explosion-proof or safety spark type measuring instruments according to user requirements.
