Maxwell vacuum gauge PM-3 manufacturers of measurement, since the instrument Maxwell vacuum gauge, Tibetan PM-3 provided by the Shanghai Automation Instrumentation Co. measured. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) is specialized in "industrial thermocouple, RTD, compensation wire, hot wire" of the enterprise, the company of "honesty, hard service" concept, to provide you with The most high-quality products and services. Welcome to inquire! Contact: China powder. In addition to using the corresponding interface is receiving a PC or PLC system controller, you can also connect the controller with the corresponding Pfeiffer performed off-line data read vacuum. DigiLineTM products corresponding Pfeiffer controller: DPG 101 McLeod gauge PM-3 wholesale, DPG 109. DPG 101 which can control a DigiLineTM vacuum gauges, vacuum gauges show a reading, DPG 109 control 9 DigiLineTM vacuum gauge, vacuum gauge display nine readings. ActiveLine corresponding series has three kinds of controllers: TPG 261, TPG 262, TPG 256 A, regardless of the ActiveLine vacuum gauge can receive on these three kinds of vacuum gauges, automatic recognition, automatic conversion PM-3, plus freezing Oil: The internal device is evacuated to a negative pressure, the public side of the hose into the frozen oil (oil loading containers should be above freezing equipment), low pressure valve opens, the use of atmospheric pressure refrigerant oil pumped into the device. The use of high pressure low table to determine the condenser cooling device, temperature of the evaporator. And refrigerant inside the device is too much or too little. Top pin off valve: recover refrigerant from the refrigeration system type often use a special valve, this valve is called top pin switch valve sales Maxwell vacuum gauge PM-3, used as follows: Remove the upper and lower flap fastening connection screw fastening on the pipeline that will be connected to the valve, then tighten the fixing screws.
