Dwyer 629HLP-15-P2-S1 is a differential pressure transmitter with a temperature range of -10 to 80°C and an accuracy of ±1% from -5 to 60°C. It has a response time of 50 ms and an IP65 enclosure rating. The transmitter provides a 4 to 20 mA or 0 to 10 VDC output signal and operates on a voltage range of 12 to 36 VDC or 12 to 32 VAC. It is compatible with gases or liquids and has a wetted material construction of 304 SS, EPDM, silicone grease, and alumina ceramic. The pressure limit is 25 bar and the process connection options are 1/4" female NPT or 1/4" female BSPT. The transmitter has a loop resistance calculation of (Supply Voltage – 8 V) / 0.02 for 4 to 20mA output and a stability of ±1% FS/year. It can be installed in any position and has burst and over pressure limits depending on the range.
