The ACD-3151H remote transmission capillary flange transmitter is a digital differential pressure transmitter product launched by our company, which adopts advanced monocrystalline silicon piezoresistive technology and has high precision and stability. This product is used to measure the liquid level, density, and pressure of liquids, gases, or vapors. It converts differential pressure signals into 4mA~20mA DC analog current signals for output, and can also achieve remote settings, monitoring, and other functions through communication devices. Suitable for demanding process industries. The product has obtained explosion-proof certification and is suitable for places with explosion-proof requirements. The product adopts a wide temperature LCD display and a metal casting shell, which can be used under harsh working conditions.
