PD121 PRESSURE TRANSMITTER FOR VISCOUS AND PASTY MEDIA

SKU: PD121

PD121 features a flush diaphragm making the device highly suitable for measurements in pasty, viscous, and contaminated liquid media compatible with stainless steel AISI 316L (1.4435) and AISI 304L (1.4307). This pressure transmitter converts gauge pressure into a 4-20 mA signal which is very common in pressure applications. Depending on the device variant, we offer transmitters for positive gauge pressure.

Product Description
    Details

    The PD121 is a robust pressure transmitter with a flush membrane made of stainless steel AISI 316L. The extreme corrosion resistance of this metal allows operation in liquid, viscous, pasty, adhesive, crystallizing, or polluted media. The flush diaphragm eliminates dead spaces, which makes the process connection easy to clean.

    Depending on the device variant, we offer transmitters for positive gauge pressure.
