Pressure Gauges with Electric Contact (Micro Switch Type)

Transcription

1 Cat.No. A6- Pressure Gauges with Electric Contact (Micro Switch Type) OUTLINE In the design of this unit,a mechanical mechanism has been built in an indicator i.e. a pressure gauge with s. At a pre-set pressure,electric signals of ON/OFF are transmitted, giving a warning of buzzer,bell,pilot lamp or being able to control the processes such as motor, pump and control valve etc. FEATURE Confirmation can be made on the pressure at measuring site. As the switching current is large,this type is best suited for direct control over machines and apparatuses. Elements are independent for indication and s. Therefore,indication after switching is correct. Adoption of a microswitch design assures you of stable switching by snap action. Indicating and setting scales are separate,resulting in being possible to set optionally. * When selecting a pressure range,select it in such a way that the working pressure is within -6% of the pressure range so that its capacity can be displayed. The setting range of pressure recommended is -% of the pressure range.at the same time,materials used for solvents are suited for gas and solvent to be measured. SPECIFICATIONS Fluid: DIA., DIA.

As a sequencer input ; Use this switch gauge in the ventilated condition. Otherwise the following might be caused. The resistance of the microswitch increases gradually as time passes. For the application in the atmosphere,especially including Si,SiO will be accumulated on the part as switch operated.then the resistance will be increased,so that switch may be not operated. Therefore,above is suggested for the application condition,including Si atmosphere. When you use this switch gauge as sequencer input for controlling,input or connect through V AC Relay.. Installation of protection circuit for In the inductive load open and close circuit,install the protection circuit to protect the. When you use the relay,choose the built-in protection circuit for the.
