Digital pressure switch
Digital pressure switch for implementing a pressure system with immersion or force pumps
3550.01.12 Connection John Guest Plug system Ø 12 mm
3550.01.20 X-Fix connection
3550.01.21 Hosetail connection
The pressure measurement occurs using a ceramic pressure transducer. The voltages produced in the pressure sensor by pressure changes in the system are transferred for evaluation, as electrical signals of a microprocessor controller. Exceptional drops in pressure in the system (a leaky valve, leakage in the system and tube positions) are, thus, detected and the pump is shut off. Water damage to the recreational vehicles can, thus, be prevented!
functions:
- leakage detection and with an automatic pump stop
- external capability for trouble indication
- manually adjustable cut-out pressure
- ceramic pressure transducer
- regulation of engine speed dependent on the amount of water removed
- plug-and-socket connection for PE tube Ø 12 mm
(variation: plug-and-socket connection for inner Ø 10 mm)
technical data's:
| W x H x D | max. 100 / 62 / 79 mm |
| voltage | voltage 10 V bis 15 Volts DC |
| stand-by currency (Pump OFF) | ca. 10 mA |
| currency (Pump ON) | 0.5 to 6 Amps (depends from used pump and system pressure) |
| overload protection | approx. 6 to 7 Amps |
| short circuit protection | given |
