Description

The digital display electric contact pressure gauge with 100mm stainless steel shell (the shell material is 304 stainless steel) is used to replace the mechanical electric contact pressure gauge. This electric contact pressure gauge is mainly to replace the traditional mechanical electric contact pressure gauge, especially suitable for use in the working conditions of frequent pressure shocks and strong on-site vibrations. It has the characteristics of anti-vibration, long life, simple operation and clear display. At the same time, this digital display electric contact pressure gauge has a variety of pressure unit switching.

Structural principle

The electric contact pressure gauge is composed of a measuring system, an indicating system, a magnetic-assisted electric contact device, a casing, an adjusting device, and a junction box (plug seat), etc. General electric contact pressure gauges are used to measure the positive and negative pressures of gases and liquid media that do not corrode copper and copper alloys. Stainless steel electric contact pressure gauges are used to measure the positive and negative pressures of gases and liquid media that do not corrode stainless steel. When the pressure reaches a predetermined value, a signal is sent, and the control circuit is connected to achieve the purpose of automatic control and alarm.

Features

●Touch keys, and with key tone, effectively improve the use of keys.

●Using 4000mAh lithium battery for power supply (ER18505H), low power consumption design.

●The battery can be replaced, which is convenient for customers to replace the battery by themselves. .

●Wide temperature temperature compensation, suitable for various harsh environments.

●Peak record, unit conversion and other functions are complete and easy to use.

●Users can set the acquisition rate, automatic shutdown time, key lock time, backlight automatic shutdown time and other parameters according to their own habits.

●11 kinds of pressure unit conversion, and the unit to be converted can be set, and the less commonly used units can be closed.

●Increased the function of restoring factory settings.

During the operation, if the user makes a mistake, such as mistakenly reset to zero under pressure, mistakenly enter the setting interface, etc. You can use this function to restore the pressure gauge to the factory calibrated data and settings.

●In order to prevent other keys from being touched, a lock key has been added.

In use, you can press the lock key, and a lock pattern will appear on the display screen to lock other touch keys, and it will not affect the pressing and use. After using it, it can be unlocked and turned off.

●The product has obtained the explosion-proof certificate, and the explosion-proof grade is EX ia IICT4 Ga

Application

The electric contact pressure gauge is widely used in petroleum, chemical industry, metallurgy, power station, machinery and other industrial sectors or in supporting mechanical and electrical equipment to measure the pressure of various fluid media without explosion hazard. Usually, the instrument is used in conjunction with corresponding electrical devices (such as relays and frequency converters, etc.), to realize the purpose of automatic control and signaling (alarm) of various gases and liquid media with measured (controlled) pressure through the instrument.
