Electronic Pressure switch for liquid, high viscosity/roiled liquid (SmartPress)
 |
| 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 |
|
|
| Protection class |
IP65 |
| Housing material |
Polybutylene terephtalate (PBT) |
| Sensing element material |
1.4571 + 1.4435 |
| Media temp. |
-20 ... 100 oC |
| Media temp. limit |
Higher temperatures are possible, provided that the limit is safeguarded by suitable measures (e.g. water tube trap) |
| Ambient temperature |

| 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. |
