The Field-Type Smart Meter (a digital indicator), Field-Type Analog Meter (a current indicator), and Multifunction Panelmeter are used in various applications in combination with a differential pressure or pressure transmitter.
- Field-Type Smart Meter (digital indicator), model No. NWS300
This is a field-mounted indicator that digitally displays the output from a transmitter. It operates only after being connected to the signal from the transmitter and does not require an external power supply.
- Field-Type Analog Meter (current indicator), model No. NWA300
This is a current indicator that displays the analog signal (4–20 mA) from a transmitter.
- Multifunction Panelmeter, model No. PCM***
This panelmeter receives analog output or pulse output from a flowmeter, pressure gauge, photoelectric switch, or other device. It is equipped with a counter function and can display either the instantaneous or the accumulated value on an LED display. Additionally, it has various output functions, a distributor function, and a preset counter function.
This single alarm indicator has universal input specifications. Input is selectable from five types of thermocouples, resistance temperature detector, and analog signal. The thermocouple input terminal has a built-in room temperature compensation circuit.
Two relay contact alarm outputs are a standard feature. The output format can be set for high and low limits, high and high high limits, and low and low low limits.
4–20 mA DC isolated output is possible as a standard feature.
Since any value between 4 and 20 mA DC can be output as a loop check function, it is not necessary to have a separate constant-current generator or similar device.
Scaling during input and output to/from thermocouples and resistance temperature detector can be set at any value between 4 and 20 mA DC.
This indicator is equipped with a large 15-mm LED display, and red or green LED can be selected according to the application.
