Imported diffusion silicon pressure transmitter 4-20mA
Product introduction
The electrical components of the pressure transmitter that feel the pressure are generally resistance strain gauges. Resistance strain gauges are sensitive devices that convert the pressure on the measured part into an electrical signal.The most used resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges.There are two types of metal resistance strain gauges, filamentous strain gauges and metal foil strain gauges.Usually, the strain gauge is tightly bonded to the substrate that produces mechanical strain through a special adhesive. When the stress of the substrate changes, the resistance strain gauge is also deformed together, causing the resistance value of the strain gauge to change, so that the voltage applied to the resistance changes.
Product features
1. The pressure transmitter has the characteristics of reliable operation and stable performance.
2. Dedicated V/1 integrated circuit with few peripheral devices, high reliability, simple and easy maintenance, small size and light weight,
3. Installation and debugging are extremely convenient. 3. Aluminum alloy die-cast shell, three-terminal isolation, electrostatic spray protective layer, strong and durable
4. 4-20mA DC two-wire signal transmission, strong anti-interference ability and long transmission distance
5. There are three kinds of indicator heads, LED, LCD, and pointer, which are very convenient for on-site reading.Can be used to measure viscous, crystalline and corrosive media
LED display
Using digital display, the numbers are more accurate and the readings are more convenient
Explosion-proof housing
The shell adopts high-strength explosion-proof design,
Stable and suitable for harsh environmental conditions on-site
3mm pressure guide hole
Effectively reduce the impact of instantaneous pressure on the internal diaphragm, reliable and flexible, and ensure sensitivity
