The SB-68 pressure transducers from Full Gauge Controls are manufactured from 316L stainless steel and offer high stability, accuracy, and reliability. All models feature a 7/16-20UNF-2B female connection (SAE ¼" standard), a 10 to 30 Vdc power supply, a 4 to 20 mA output signal, 28 mA current limiting (linear output up to 1.5 times the nominal range), minimum insulation resistance of 100 MΩ, and operating relative humidity from 0 to 95%. They are resistant to interference and vibrations and are available in different pressure ranges. Check out the main characteristics of each model below:
