Product Description
Product overview
HM41 intelligent digital pressure switch / vacuum pressure switch is a high-end high-standard supporting accessory designed for customers. It is developed and manufactured by our company in cooperation with foreign companies. The pressure signal is sent to the microprocessor by using high-precision microprocessor-controlled pressure gauge and high-precision signal processor and the pressure sensor used is the high-precision high-stability product of HELM company, which is compatible with the intelligent pressure switch and electronic equipment.
This intelligent digital pressure switch is an intelligent control instrument integrating pressure measurement, display and control. It is featured by simple operation, good shock resistance, high control precision, adjustable control range and long service life.
It has excellent circuit design and high stability, takes full account of the complexity of the automation site, and is provided with strong anti-interference protection, anti-surge protection, reverse connection protection, etc.. This product can carry signal output, such as 4-20mA, 0-5VDC, RS485 to meet different industrial and mining needs.
