The 230-WE100 Barometric Pressure Sensor covers a pressure range from 800 to 1100 mb. The barometric pressure transmitter is fully temperature compensated within an operating range of -40° to 65° Celsius. The output is 4-20 mA with a two-wire current-loop configuration. The sensor is supplied with 25' of marine grade cable, with lengths up to 500' available.
The 230-WE100 produces a 4-20 mA output signal which is an industrial standard signal for process control monitoring. Most PLCs (Programmable Logic Controller), RTUs (Remote Telemetry Unit), and data acquisition systems accept this signal directly. If a voltage signal is required, the sensor output may be converted by reading the voltage across a precision resistor in series with the signal wire. When the 4-20 mA signal is dropped across a 250 ohm resistor, the output will be 1 to 5 Vdc. 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.
