Sensotec's Model 424 & 425 Hammer Union pressure transmitter are rugged sensors designed specifically for use with 1502 and 2202, two-in. wing unions in the demanding environment of drilling installations. Typical high-pressure applications include mud logging, cementing, fracturing, acidizing, nitrogen pumping, and other upstream well servicing applications. The Model 425 is available in ranges from 0-5,000 to 15,000 psi. The Model 424 is available in ranges from 0-15,000 to 20,000 psi. Both the 425 and 424 deliver accuracy of 0.2% (BFSL). Standard output is 4-20 mA (2-wire) with a supply voltage of 9-28 VDC. Each unit is RFI / EMI protected. Operating temperature is from -45 to 200 degrees F. The "ESX" Power sections provide high torque at very low speed for mud motors.
