Temperature and Humidity / Dew Point Transmitter / Switch Series HVAC40
Senseka (formerly Delta Ohm)
High cost-performance transmitter with excellent long-term stability.
▲0/4～20mA/0～10V/RS485 Modbus-RTU/Relay output ▲Front blind plate (standard) or LCD display option ▲Three types of probe shapes available: downward, rear, and separated ●Designed and developed based on 40 years of experience from Senseka (formerly Delta Ohm), pursuing accuracy, stability, simple installation and operability, and flexible communication connectivity, this humidity, temperature, and dew point temperature transmitter and hygrostat is built for long-term use. ●In addition to 0/4–20mA and 0–10V analog outputs, and RS485 Modbus-RTU, there is also a model with SPDT relay output for external device control. ●Probe shapes can be selected from rear probe, downward probe, and cable-attached separated probe. ●In addition to the standard model with a blind plate on the front, all models have an LCD display option.
