The PE 74 temperature protection device is used to shut off the sample flow in the event that the sample temperature rises above 55°C due to a lack of cooling water (other trigger temperatures are also available on customer request).
The maximum sample pressure is 200 bar at 100°C.
- Fail-safe, as no auxiliary power is required
- Evaluation by optional switching contact
- Reset possible without removal
Safety shut-off systems are used to shut off the sample flow when the sample temperature is too high, such as when the cooling water fails or when the sampling cooler is defective. They prevent extremely hot sample material from flowing through the measuring instruments and destroying them or injuring operating personnel.
PE 74
AutoSafe mechanical safety shut-off system. It uses a thermostat system for the switching operation and is therefore independent of a power supply. It can be used for pressures up to 300 bar. A signal contact for fault indication or as a switching contact is available as an option.
PE 79
Electronic temperature switching device TempControl. The TempControl detects the temperature at the sample outlet and activates the associated safety shut-off system when a freely selectable limit temperature is exceeded. The system remains closed until the fault has been rectified and the corresponding acknowledgement has been received. During the fault, a potential-free contact signals a corresponding alarm.
PE 73/79
Elektrisch angetriebener Absperrkugelhahn mit Temperaturschaltgerät TempControl. Das klassische Absperrsystem mit Schließzeiten < 15 s ist für den Einsatz im Hochdruckbereich bis 400 bar geeignet.
Alternativ können außerdem Pneumatikventile (Druckluft gesteuert) mit Schließzeiten < 1 s eingesetzt werden.
PE 76/79
Solenoid valve with TempControl. For use in the low-pressure range for pressures below 40 bar.
(Also available for high temperature range)
