SP21 – Economical Transmitter (mA and Voltage outputs)
The SP21 pressure transmitters are designed to measure the pressure of liquids and gases. They feature MEMS (Micro-Electro-Mechanical Systems) Technology, 316SS piezoresistive silicon chips, polarity protection and excellent long term stability. These highly reliable sensors are available with Gauge or Absolute pressure ranges, a variety of signal outputs (0.5 to 4.5Volts, 1 to 5Volts, 0 to 5Volts or 4 to 20mA), are fully temperature compensated and can be powered from 8 to 30Vdc.
Technology:
As pressure increases within a vessel, a displaced electrical charge accumulates on the opposing surface of the piezoresistive cell. This generates an output signal, which is converted to a standardized Voltage or 4-20-mA (2 wire) signal that is directly proportional to the pressure applied. Standard connections are 1/4”, 1/2” (BSP or NPT), but separate adaptors can be ordered to conform to individual process requirements.
