Pressure sensors
Electronic Pressure switch, with LCD 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
Switch + Transmitter, PST ...-models
Electronic Pressure switch for liquid, high viscosity/roiled liquid (SmartPress)
Protection class IP65
Housing material Polybutylene terephtalate (PBT)
Sensing element material 1.4571 + 1.4435
Media temp. -20 ... 100

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

Switch function/capacity PST-models: Open collector switch max. 250 mA dc at 14 ... 36
Vdc. 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.
