Humidity transmitters for accurate control, with Modbus or analogue output
OJ Air Humidity
The OJ Air Humidity range covers both general and specialized needs. Our HTH series of humidity transmitters are ideal for any application where you need a humidity sensor. Available in versions for installation in rooms or ventilation ducts, these humidity transmitters measure the current air humidity with great accuracy so that your demand-controlled ventilation system can respond quickly and efficiently to changing conditions.
For more specific tasks, we offer our NVP moisture alarm relays as well as our EHP controllers, which are used with analogue humidity transmitters to control humidifiers and/or dehumidifiers.
Measuring humidity and temperature – Modbus output
Our HTH-62xx humidity transmitters are designed for duct installation and are capable of measuring humidity and temperature. Data is transmitted via Modbus, and flexible length options make these humidity sensors suitable for ventilation systems on any scale.
Measuring humidity – Analogue output
The HTH 61xx range of humidity transmitters also includes versions with analogue 4-20 mA output. These specialized sensors cover a wide measurement range from 0 to 100% RH.
Water leak sensor
The NVP is a moisture alarm relay used to detect water leaks and excessive moisture. Ideal where there is a risk of condensation or burst water pipes – and you want reliable notification.
The EHP series of controllers are used with analogue humidity transmitters (0-20 mA) to control a humidifier/dehumidifier. Combine in series to ensure that your environment maintains exactly the level of humidity you want.
