MIEPL 501P Smart Pressure Transmitter uses as its measuring principle, the well known and field proven technique of sensing a crystal silicon chip and a diaphragm micro-machined into the chip, enhanced by microprocessor based electronics.
Designed for process control applications, these 2-wire transmitters generate a 4-20 mA signal proportional or characterized to the applied pressure. This signal can be transmitted over a pair of twisted wires through long distances (limited only by the wire resistance and load). Remarkable features of the transmitters are its 0.075% inaccuracy and non-linearity(optional), 20:1 rangeability, compactness and light weight. |
