product description Pressure transmitter TST-SiAl
Pressure transmitters of the TST-SiAl series are used in all measuring tasks in which liquids and non-aggressive gases are to be measured accurately and reliably even in very small millibar ranges. Examples are the ventilation technology, the level monitoring of small containers, the food industry or in general in plant construction, automation technology or other industrial applications. The TST-SiAl uses a silicon measuring cell which is suitable for media temperatures from -40 to + 85 ° C. Output signal, process connection and electrical connection can be flexibly combined and selected from the customary market variants.
