Electronic Pressure switch for gas, low viscosity liquid (SmartPress)
Electronic Pressure switch, with LED display for the field of plant construction, fluidics, process
technology, and pneumatics, as well as in the monitoring and control of pumps and compressors.
Models available with the following output types:
all models: switch output open collector; 14..36 Vdc, 250 mA
PST -series: transmitter output; 0..10 Vdc or 4..20 mA
PST..R -series: relay output with gold plated SPDT contact
Protection class IP65
Housing material Polybutylene terephtalate (PBT)
Media temp. -20 ... 100 o C
Media temp. limit Higher temperatures are possible, provided that the limit is
safeguarded by suitable measures (e.g. water tube trap)
Ambient temperature -20 ... 60 o C
Switch function/capacity PST..R-models with relay contact output, 1 x SPDT, material silver
gold plated. Capacity resistive: 24 Vdc, 60 mA / 230 Vac, 6,5 mA.
With bigger loads, the gold layer will disappear, the capacity with
the silver contacts is: 230 Vac 3(1) A.
Sensing element material 1.4571 + 1.4542
