The 266 series pressure transmitter combines enhanced electronic pressure measurement with a unique HMI. The industry’s first through the glass (TTG) technology lets operators configure the transmitter without opening the cover—even in hazardous rated areas. The local HMI display makes configuring the transmitter as simple as working a cell phone.
The enhanced DPharp EJA series transmitters have the same high-speed response and multi-sensing functionality as the high-end DPharp EJX series. They can simultaneously measure differential and static pressure, and have a response time of 90 ms. Compact/lightweight in design, they weigh 30% less than the non-enhanced version. They are IEC61508-compliant and certified to SIL 2.
