Humidity and Temperature Controllers Selection Guide: Technical Criteria & Application Standards
Humidity and Temperature Controllers selection guide: technical parameters, mounting and compliance standards, and Enda, GEMO, Tense comparison.
Humidity and temperature controllers are devices that display the relative humidity and ambient temperature read from the sensor and switch output contacts on and off according to their setpoints; they are selected by supply voltage, mounting style, sensor structure, number of outputs and communication needs. They are used in incubators, greenhouses, drying rooms, warehouses and air conditioning systems to switch a heater, cooler, humidifier or dehumidifier on and off. The category includes the digital and sensor-equipped models of the Enda EHTC series and GEMO and Tense devices; options with 230 V AC, 90-250 V AC and 10-30 V DC / 8-24 V AC supply and RS485 Modbus communication are available. In ON-OFF operation, hysteresis determines the difference at which the output switches on and off around the setpoint. The sensor does not come with the device in every model; for the Enda EHTC7425A, the manufacturer states that the sensor must be ordered separately. A controller with only a temperature input cannot measure relative humidity, and a humidity and temperature transmitter gives a measurement signal without switching a load; neither is a substitute for these devices. The Humidity and Temperature Controllers category on Welibaba includes 16 active models from leading manufacturers such as Enda, GEMO, Tense.
Key Technical Parameters for Selecting Humidity and Temperature Controllers
To specify the right Humidity and Temperature Controllers model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Supply Type | 10 - 30VDC / 8 - 24VAC, 100..240 VAC, 230 V AC, 90–250 V AC | Verify against project schedule and load calculation |
| Communication Type | RS485 Modbus, Yok | Verify against project schedule and load calculation |
| Storage Temperature | -10 °C .. 60 °C (buzlanma olmadan), -25 ... +70°C | Verify against project schedule and load calculation |
| Relative Humidity | 30 °C'ye kadar %80, sonra doğrusal azalarak 50 °C'de %50 (yoğunlaşmasız), 31°C'ye kadar %80, sonra lineer olarak azalıp 40°C'de %50'ye düşen nemde çalışır | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Temperature and Heat Control Devices.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Analog Temperature Controllers, Digital Temperature Controllers.
