ACT115 Conductivity Transmitter with 4–20 mA Output
The ARTang ACT115 is a panel-mount conductivity transmitter for water treatment, process-water monitoring and OEM equipment. It combines a local LCD display, 4–20 mA output and a high-limit relay for measurement indication, remote monitoring and threshold-based control.
Electrode Cell Constants: 0.1, 1.0 or 10.0 cm⁻¹
Analog Output: 4–20 mA
Control Output: High-limit relay
Temperature Compensation: Automatic
Panel Cutout: 45 × 92 mm (H × W)
Power Supply Options: 110 V AC, 220 V AC or 24 V DC
Product Description
The ACT115 conductivity transmitter connects to a compatible conductivity electrode to provide continuous measurement of water or compatible aqueous process liquids. The 4–20 mA signal sends the measurement to a PLC, recorder or supervisory system. A high-limit relay provides an output for an external alarm or control circuit when conductivity reaches the configured threshold.

Frequently Asked Questions
Yes. Its 4–20 mA output can connect to a compatible PLC analog input. Ensure the electrical connection and measurement scaling match the PLC input configuration.
The specified control output is a high-limit relay. If your application requires additional alarm or control outputs, include those requirements in your inquiry.
A sensor’s range does not increase the transmitter’s range. The ACT115’s listed maximum conductivity range is 0–200 mS/cm with a 10.0 cm⁻¹ electrode. Sensor wiring and temperature element compatibility must also be confirmed.
