This DP transmitter has SIL 2 certification

| By Mary Page Bailey and Gerald Ondrey

The new model DPT-20 differential pressure (DP) transmitter (photo) is suitable for many industrial processes. As a SIL-2 certified instrument, it meets the highest safety requirements. The compact transmitter operates with an accuracy of <±0.065% of span. Due to a three-dimensional temperature compensation on adjustment, it provides a reliable measuring result, even under unfavorable ambient conditions. The DPT-20 is available with measuring ranges between –10 and 10 mbars, and –16 and +16 bars, and is designed for a static pressure of up to 400 bars. There are three communication protocols available for integration into existing systems. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
