Dwyer 636-2 Fixed Range Pressure Transmitter is a reliable and accurate device with a temperature range of -40 to 140°F (-40 to 60°C) for electronics and -40 to 212°F (-40 to 100°C) for the process interface. It has an accuracy of ±0.30%, making it highly precise. With a power requirement of 12 to 30 VDC, it offers reverse polarity protection. The NEMA 4 (IP56) enclosure rating ensures protection against dust and water. The 4 to 20 mA DC output signal provides efficient data transmission. It can handle liquid, gas, and vapor, with a pressure limit of 300% of the upper range limit. The 316 L SS wetted material ensures durability and resistance to corrosion. The 1/2" female NPT process connection makes installation easy. The thermal effect is ±2.0% per 50°F (28°C) between -20 and 180°F (-29 and 82°C). With a loop resistance of 900 Ω max, it ensures efficient operation. The stability of ±0.5% for six months ensures consistent performance. The fill fluid used is DC 200 Silicone.
