Swiss-Built Series 35X HT-HTT High temperature high accuracy analog digital output pressure transmitter Piezoresistive pressure transmitter for applications in bio-reactors or autoclaves. The transmitter is compensated up to 150 °C and may be operated continuously or sterilised at this level, including the special circuit electronics. The transmitters are supplied in absolute or gauge versions, with current or voltage output. The sensing component is a micro-machined silicon pressure chip of high sensitivity. An independent temperature sensor is integrated on the surface of the silicon chip.

Series 23 (S) Ei, 25 (S) Ei and 26 Ei pressure transmitters are all ATEX approved for use in Hazardous Areas where there is a high risk of explosion. Series 23 Ei / 26 Ei The Series 23 Ei / 26 Ei achieve high stability (especially in low pressure ranges) with large piezoresistive capsules and stress-free, floating mountings with O-rings. Series 23 S Ei / 25 Ei / 25 S Ei
The 23 S Ei / 25 Ei / 25 S Ei offer a complete range of „Ported“ and „Flush Diaphragm“ pressure transmitters for ranges of 1bar and above. Still giving high stability and accuracy but without any internal O-rings. This is achieved using either an all welded 316L stainless steel housing and diaphragm or an all welded 316L housing fitted with a brazed Nickel diaphragm.
– A complete range Absolute, barometric, gauge (positive and negative). 16 nominal pressure ranges. Current or voltage output.
– Flexibility A modular concept is used, with fast and economical production achieved by using off-theshelf sensors. Numerous options and variations are available to meet customers’  specific requirements: Pressure ranges, mechanical- and electrical interface, process- and plug connection, signal outputs etc.
– Reliability / Quality 
Each transmitter is subjected to severe test- and calibration procedures. Transmitters are manufactured and tested according to ISO 9001.
