Description
The MANOCOMB®-IP65/XI is a precision pressure switch for measuring pressure, differential pressure and vacuum of gasous or liquid, also chrystallizing and highly viscous media.
Escpecially for hazardous area.
Operating Principal
The operation is based on force-balance - per change-over contact a metal bellow is available, which is opposed by a precison spring with an adjustable force.
Once the process pressure overcomes the set force the change-over is triggered.
The contact adjustment is done by removing the cover and turning the thumb wheel to the desired set point.
The set point adjustment can be comfortably read from the set point scale. No reference instrument is needed.
The measuring system, which actuates the switching contact works friction-free, resulting in minimal wear. No maintenance or spare parts are needed!
Integrated Pressure Gauge
The optionally integrated pressure gauge (class 1.0) visualizes the actual process pressure right next to the set point indicator.
