Product Description
The single crystal silicon differential pressure transmitter is used to measure the liquid level, density, or pressure of liquids, gases, or steam, and then convert it into a 4-20mADC HART current signal output. It employs high-precision single crystal silicon technology, achieving a measurement accuracy of up to 0.075 class, and features a unique dual overload protection film design, with unidirectional overpressure tolerance up to 40MPa.
Product features:
1. High performance and high precision. Utilizing high-performance single-crystal silicon differential pressure technology, the measurement accuracy reaches 0.075%.
2. High range migration ratio: 10:1.
3. High-brightness liquid crystal display, operating in a wide temperature range of (-40 to 70 ºC).
4. Wide range detection, with a detection range of 1 kPa to 3 MPa.
5. High-performance static pressure testing, with an electrostatic pressure error of ±0.05% per 10 MPa.
6. Dual overload protection diaphragm design, with a single-phase overpressure capacity up to 42 MPa.
