Series 981 universal pressure transmitter for 0 - 100 mbar

Analogue pressure transmitters can be used in a variety of applications. The installation site, however, determines the maximum size and the selection of materials for the diaphragm and housing. It is therefore ideal when analogue pressure transmitters adapt individually to their applications. For this reason, we have expanded our broad range of compact pressure transmitters to include the analogue pressure transmitter 981 (pictured). You, the user, can take advantage of decades of experience with different materials and their use in a wide variety of media. Tried and tested diaphragms and a huge selection of screw, flange and plug connections made from a wide variety of different materials are available for a number of different applications. Measuring just 45 mm in diameter and 59 mm in height (including a 15 mm connecting piece), the sensor is very compact and can be easily integrated anywhere. Boasting a comprehensive range of mounting brackets, it can also be quickly installed in a customised installation position.

The pressure transmitter features a selectable measuring range between 0 and 100 mbar at a linearity of smaller than +-1% FSO BFSL @ 20°C. This measuring range is required by the customer and is individually preset upon delivery, allowing the pressure sensor to be installed immediately for the end customer’s application. The supply voltage of 24 VDC, at < 20 mA current consumption, as well as the output signal, (min. 10 kOhm load), is transmitted via a four-pin standard M12 flange plug (other plug variations available upon request). The response time is 500 ms. The sensor can provide either a three-wire output signal with 0-10 VDC or a two-wire output signal with 4 - 20 mA. Diaphragms made of different materials are available for monitoring the overpressure and underpressure of liquid, gaseous and aggressive media in the range of -20 to +85°C. In addition to NBR (Nitrile Butadiene Rubber), silicone for food applications and fluorocarbon rubbers (FKM) or ethylene propylene diene rubber (EPDM) for aggressive media are also available; other materials available on request. For pressure connections, users can choose between metals like brass (incl. nickel-plated) and stainless steel, and in the case of plastics between polyamide (PA), polyvinyl difluoride (PVDF), polyphenylene sulphide (PPS) and other types. Standard hose supports with 5, 6.5 or 10 mm diameters and threaded couplings in M10x1, G1/4 and G1/2 are available. Special versions as flange or specific threads are available upon request at any time.
