#Barometric pressure weather indicator series

The resistor is placed between this input and the ground terminal of the datalogger's battery. The 4-20 signal wire is connected to the datalogger voltage input terminal. If the 4-20 mA signal is dropped across a 125 ohm resistor, the output will be halved to 0.5 to 2.5 VDC. Since Ohms Law states that V = IR, if the 4-20 mA signal is dropped across a 250 ohm resistor, the output will be 1 to 5 volts DC.

If the system only accepts voltage signals, the sensor output must be converted to a voltage signal by reading the voltage across a precision resistor in series with the signal wire. Most PLCs (Programmable Logic Controller), RTUs (Remote Telemetry Unit), and data acquisition systems accept this signal directly. WE100 Barometric Pressure Sensor produce a 4-20 mA output signal.Д¤-20 mA is an industrial standard signal for process control monitoring. Barometric pressure transmitters are also used for many other applications including ocean buoys, ships, checking engine performance, airports, and many more. Most weather stations include a barometric pressure sensor as one parameter they monitor. Changes read by a barometric pressure meter or transmitter indicate weather front movement. One important parameter in monitoring weather systems is barometric pressure. The sensor output is 4-20 mA with a two wire configuration Global Water WE100 Barometric Pressure Sensor

The sensor is mounted on 25' of marine grade cable, with lengths up to 500' available upon request. The barometric pressure indicator is fully temperature compensated within an operating range of -40 to 65 C.

Highly accurate Barometric Pressure Sensor covers a pressure range from 800 to 1100 mb.
