Modular pressure transmitters for harsh environments
DST P500, DST P507 and DST P550
The P500 / P507 / P550 utilizes the thin film strain gauge sensing technology, incorporating an hermetically sealed design with no
internal sealing required. Designed for harsh environments, a rugged 304 stainless
steel housing surrounds the P500 / P507 / P550 transducer.
The P500 / P507 /P550 small, compact design as well as its low overall weight makes it ideal for applications with spacing and weight limitations. This easy-to-use sensor is media resistant,
which allows it to be used for a broad range of liquid and gaseous media. It can be used at high operating temperatures and has internal temperature compensation.
Highly reliable, the P500 / P507 / P550 provides accurate, high pressure measurements every time.
P507 is suitable in applications where cleanliness is a must. All transmitter parts in contact with the medium meet the cleanliness requirements according to the ISO 15001 standard.
P550 with integrated pulse-snubber is suitable in applications with severe medium influences like cavitation, liquid hammer or pressure peaks.
