Differential Teletransmission Pressure Gauge
Application
This pressure gauge is a two-wire safety type explosion-proof pressure gauge, used to measure the pressure of liquids, gases and vapors that are not corrosive to copper and its alloys. When it equipped with a damper, it can measure the pressure of pulsation, impact, and sudden unloading of the medium. With a differential transmitter in the gauge, it can switch the measured pressure to 4~ 20mA electric current signal, and transmit to the secondary instrument far from site for concentrated examination and remote control. It can be combined with the display, record, and adjustment instruments in the DDZ-III electric unit combination instrument to form an automatic recording, adjustment, and control system. It is suitable for petrochemical, metallurgy, power station, light industry and other industries, and is especially widely used in constant pressure water supply.

■Please read the instructions carefully before use.
■Please use Hakin special medium pressure gauge when measuring the medium that is explosive or corrosive, easy to crystallize or solidify.
■It is necessary to add a protective device for the pressure gauge in an environment with a sharp pressure change or vibration or pulsation.
■When installing or disassembling, don't pull the case of the gauge by hand, use a special wrench to install or disassemble.
■The pressure gauge should be installed horizontally or vertically.
■The normal working environment temperature of the pressure gauge is -40°C~ + 70°C, and the relative humidity is not more than 85%.
