these piezoresistive pressure transmitters with pressure proof housing are approved for use in explosion risk areas of group ii. they provide stable and accurate measurements of absolute and gauge pressures of liquid and gaseous media in the pressure range between 0,1 and 300 bar.

analog transmitters, series 23 ed and 25 ed:
this series is based on the stable piezoresistive transducer with analog electronics. the zero point and sensitivity, and the temperature coefficients for the zero point and sensitivity, are compensated by resistors and/or potentiometers.

digital transmitters series 33 x ed and 35 x ed:
this series features microcontroller-based electronic evaluation to ensure maximum accuracy. each transmitter is gauged across the entire pressure and temperature range. this provides the basis for calculating a mathematical model that corrects all reproducible errors. the pressure value can be read via the interface and at the same time it is also available in analog form as a 4…20 ma or 0…10 v version.

piezoresistive pressure transmitter series 21 c

for industrial applications, ratiometric output

the c-series transmitters are noted for their ability to deliver high accuracy over a wide temperature range. this is achieved by means of mathematical modelling of the sensor characteristics and digital compensation. in order to do this, each transmitter is gauged over pressure and temperature, programmed and checked after calibration in the same test set-up.

the modular design of the series 21 c and the extensive vertical range of in-house manufacture provide a high degree of flexibility. the company can adapt to customer requests, even with large production batches. the extensive standard range of connectors and pressure connections means that a cio measuring cell (chip-in-oil) can be welded in from stock if small numbers are involved, and then calibrated to the required temperature range.

piezoresistive transmitters series 35 x ht(t)

for applications in bio-reactors or autoclaves

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.

each series 30 transmitter also integrates a digital interface (rs485 halfduplex) which you can make use of: connect the transmitter to a pc or laptop via a converter rs232-rs485 (i.e. k-102, k-104 or k-107). two programs are offered: read30 and prog30.
