Dwyer 681-42 Sanitary Pressure Transmitter is a reliable and accurate device, capable of measuring pressure in a wide range of compatible liquids and gases. With a temperature range of -40 to 260°F (-40 to 125°C), it can withstand extreme conditions. It requires a power supply of 9-30 VDC and generates a 4-20 mA output signal. The transmitter features a fast response time of ≤10 ms and has zero and span adjustments of ±0.5 mA. It is equipped with a 1/2" conduit fitting and strain relief with a 15 ft (4.5 m) cable for easy installation. The wetted parts are made of 316L Stainless Steel, ensuring durability and resistance to corrosion. Its accuracy of ±0.20% FS, including non-linearity, hysteresis, and non-repeatability, guarantees precise readings. The pressure limit and thermal effects are specified on the catalog page, and the transmitter has a loop resistance of 800 ohms. The connection is made through a 2" or 1-1/2" Sanitary Clamp fitting with male NPT. Additionally, the clamping effect is minimal, with a zero and span shift of ±0.15% FS for ranges up to 30 psi and ±0.25% FS for ranges greater than 30 psi.
