HTRT10A(-D)

Product catalog summary

Overview
The HTRT10A(-D) series consists of humidity and temperature transmitters designed for indoor environments. These devices are suitable for wall mounting in HVAC systems and offer good long-term stability.

Specifications

Output Signal: Analogue, 0...10 V DC for both temperature and humidity.
Temperature Range: 0...50°C with PT1000 class DIN B sensor.
Humidity Range: 0...100% RH with a capacitive thin-film element.
Supply Voltage: 24 V AC ±10% or 15...35 V DC.
Power Consumption: Less than 1 W.
Protection Class: IP30.
Dimensions: 85 x 100 x 30.5 mm.
Color: Signal white RAL 9003.

Functionality
The transmitters provide a 0...10 V signal proportional to the measured temperature and humidity. The PT1000 sensor requires calibration with a controller due to internal warm-up. The humidity sensor offers quick response to changes and excellent stability.

Display Models
The HTRT10A-D model includes an LCD display that alternates between showing temperature and humidity.

Technical Data

Humidity Sensor: Capacitive, accuracy ±3% RH at 20°C.
Temperature Sensor (1...10 V): Accuracy ±0.4°C at 20°C.
Temperature Sensor (PT1000): Accuracy ±0.3°C at 20°C.

Installation and Wiring
The device connects via screw terminals with a maximum capacity of 1.5 mm² (AWG 16). GND and G0 are internally connected.

Models

HTRT10A: Standard model without display.
HTRT10A-D: Model with display.

Compliance
This product carries the CE mark, ensuring compliance with European standards.

Catalog excerpts

HTRT10A(-D) Humidity and temperature transmitters A range of room transmitters for measuring humidity and temperature in indoor environments. Analogue output signal Temperature sensors, 0...10 V DC referring to 0...50°C and PT1000 class DIN B Output signal humidity, 0...10 V DC referring to 0...100 % RH Humidity, 10...90 % RH Temperature, 0...50°C Good long-term stability Supply voltage Transmitters intended for wall mounting in HVAC systems. The transmitter uses a supply voltage of 24 V AC ±10 % or 15...35 V DC. It automatically detects and adapts to the supply voltage connected. Temperature sensors The unit has built-in 0…10 V and PT1000 temperature sensors, working range 0...50°C. Note! The PT1000 sensor is not compensated for internal warm-up. The passive temperature output must be calibrated with a controller. Display (-D models) Display models have an LCD display showing temperature and humidity in an alternating series. Relative humidity The transmitters have a capacitive thin-film element that provides a 0...10 V signal proportional to the relative humidity in the range 0...100 % RH. The measuring element responds quickly to changes in humidity and has excellent long-term stability. HEAD Phone: Web: E-Mail:
