How do you adjust a Danfoss pressure switch?
To make adjustments to your low side, use a screwdriver to turn the spindle clockwise to lower the value and counterclockwise to raise the value. To make adjustments to your differential, turn the spindle clockwise to raise the value and counterclockwise to lower the value.
How does a Danfoss pressure switch work?
Danfoss pressure switches are electromechanical controls and limiters, that control the pressure of air and liquids within a given pressure range. All contact systems in Danfoss regulating units incorporate a “snap-action” system that maintains the contact force until the moment of contact break.
What is KP in pressure switch?
KP thermostats are single-pole, double-throw (SPDT) temperature operated electric switches. KP is used for regulation, but can also be applied in safety monitoring systems. With the KP pressure switches you get great reliability and long service life due to the snap-action function ensuring ultra-short bounce times.
What is pressure switch range?
Operating pressure ranges from 50 to 18,000 psi and accuracy is to ± 0.5%. Diaphragm piston switches are equipped with an elastomeric diaphragm which acts on a piston. The piston then actuates the switch. Their operating pressure is from vacuum to 1600 psi and accuracy is to ± 0.2%.
How do you adjust cut-in and cut-out pressure?
Adjusting the Cut-In Rotate the range nut in a clockwise direction for higher cut-in pressure and counter clockwise for lower cut-in pressure. Note: changing these settings DOES NOT change the differential.
What is range and diff in pressure switch?
Glossary of Switch Terms: Range – The span of differential pressures or flow rates within which the sensing element of a given switch can be set to actuate an electric switch. Set or Actuation Point – The exact air pressure or flow rate which will cause the electric switch to actuate.
How does a Pressostat work?
A pressure switch is a device that operates an electrical contact when a preset fluid pressure is reached. The switch makes an electrical contact on either pressure rise or pressure fall from a certain preset pressure level.
