Vibrating level switches for bulk solids with high process temperatures up to 250°C
The SHT-series was especially designed for applications where very high
process temperatures up to 250°C are present. The instruments are
based on the successful LevelSwitch-series and likewise are applicable
for all kinds of powdered, grained or granular solids with minimum
densities of 20 grams per litre and max. grain sizes of 40mm.
A completely new developed piezo system allows the use of the SHT-series
at applications with high process temperatures up to 250°C.
The SHT-series is available in 3 different models
- SHT120 standard model, fix insertion length approx. 184mm
- SHT130 welded pipe extension, insertion length up to 2000mm
- SHT140 threaded pipe extension, insertion length up to 4000mm
Each model is available either for process temperatures up to 200°C or for process temperatures up to 250°C
Advantages
- the new piezo system allows process temperatures up to 250°C
- high sensitivity: even very light materials with densities down to 20 grams/litre can be detected
- applicable for powders as well as for materials with grain size up to 40mm
- the unique design with the single diamond shaped vibrating blade makes the SHT work reliably without malfunction; the single blade design has the advantage that material cannot build a bridge over the two blades of instruments with fork design thus causing false alarms; also materials cannot be squeezed between the two blades
- the diamond shape helps that material can easily flow over the vibrating blade and prevents that material deposits cause false signals
- the complete probe is made out of stainless steel, the electronics is mounted inside an aluminium enclosure, protection IP66 / IP67
- developed and manufactured at PTL in Germany according to DIN EN ISO9001:2015
