Convert pressure into milliamps (mA), an analog electrical signal, with a pressure transmitter. Products vary by psi range, accuracy range, submersibility, output and temperature range, among other considerations. Or, if you'd rather convert pressure into volts (V) or millivolts (mV), try a pressure transducer). These products are used in many industries, including liquid pressure fields such as hydraulic or water pressure applications related to industrial machinery, steel manufacturing, rubber manufacturing, wastewater treatment, automotive and more.
