The ACD-3151H electric differential pressure 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 4-20mA DC analog current signals for output, or can achieve remote setting, monitoring, and other functions through RS485 communication. Suitable for demanding process industries. The product has obtained dual 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.
