Digital display electrical contactpressure gauge Also known as digital pressure controller or digital pressure relay, it has setting and control functions. The upper and lower limits can be set within a small interval, and the alarm can set the delay. It is the preferred instrument for precision measurement control. It can supplement the shortage of traditional mechanical electric contact pressure gauge in measurement accuracy, control sensitivity and service life.Electric contact pressure gauge Imported high-quality pressure sensor chip, high precision and high stability can meet the different needs of customers. The instrument undergoes strict precision temperature and linear compensation, adopts CPU modular signal processing, outputs 4~20mA standard signal, plus setting control, can The control point can be set arbitrarily, which can realize the purpose of detecting, displaying, outputting, alarming, controlling and data transmission of medium pressure. It can replace ordinary pressure transmitter and traditional mechanical electric contact pressure gauge, widely used in petroleum and chemical industry. , electric power, environmental protection, automatic water supply, secondary water supply and other fields in the field of pressure measurement of various gases and liquids.

Features:

Large screen; the LCD  display includes digital visual display and analog dynamic bar reference display. The readings are straightforward.

A backlight can be added to facilitate nighttime readings.

High precision; advanced microprocessor, professional diffused silicon sensor, stable performance and high precision.
