Exploring the Benefits of Pressure Transmitter Working Principle PPT for Wholesalers
Wholesaler 1: Hey, have you heard about pressure transmitters? Wholesaler 2: Yeah, I’ve heard of them. What are they? Wholesaler 1: Pressure transmitters are devices that measure the pressure of a fluid or gas and convert it into an electrical signal. They’re used in a variety of industries, from automotive to aerospace. Wholesaler 2: That sounds interesting. What’s the working principle behind them?Understanding the Different Types of Pressure Transmitter Working Principle PPT for Wholesalers
Wholesaler 1: Hey, what do you know about pressure transmitters?| Measuring medium | Gases, vapours, liquids |
| Inaccuracy | ±0.075% |
| stability | ±0.1%/3 years |
Wholesaler 1: That’s interesting. What are the different types of pressure transmitters?
Wholesaler 2: There are several types of pressure transmitters, each with its own working principle. The most common types are capacitive, piezoresistive, and thermal.
Wholesaler 1: Can you explain how each one works?
Wholesaler 2: Sure. Capacitive pressure transmitters use a capacitor to measure pressure. The capacitor is filled with a dielectric material, and when pressure is applied, the capacitance changes. This change is then converted into an electrical signal.
Piezoresistive pressure transmitters use a strain gauge to measure pressure. The strain gauge is attached to a diaphragm, and when pressure is applied, the diaphragm deforms, causing the strain gauge to change resistance. This change is then converted into an electrical signal.
Finally, thermal pressure transmitters use a thermistor to measure pressure. The thermistor is exposed to the pressure, and when pressure is applied, the thermistor’s resistance changes. This change is then converted into an electrical signal.
