Relative humidity and temperature transmitters with digital or analogue output

Product catalog summary

Overview: The document provides detailed specifications and installation instructions for the HD9817 series of dual relative humidity and temperature transmitters, designed for various applications including HVAC, environmental monitoring, and more. These devices are housed in IP65 stainless steel, making them suitable for harsh environments.

Specifications: The transmitters offer both analogue (0...1V) and digital (RS232C, USB) outputs. They feature a capacitive humidity sensor and a Pt100 temperature sensor, with optional NTC 10kΩ for specific models. The measuring range for humidity is 5...98% RH and for temperature is -40...+60°C, extendable to -20...+80°C upon request. Accuracy is ±2% for humidity and ±0.2°C for temperature.

Models and Outputs:

HD9817T1 and HD9817T1.1: Analogue output, powered by 5-30 VDC.
HD9817T2: RS232C output, powered directly from PC.
HD9817T3: USB output, powered directly from PC.
HD9809T: Passive transmitter with 0-1 VDC output.

Installation and Connections: The document details the wiring connections for each model, emphasizing the need for proper installation of USB drivers for models with digital outputs. Various mounting options are available, including wall mounts and duct flanges.

Calibration: The transmitters are factory calibrated for humidity. A calibration procedure is included on the supplied CD-ROM, but no procedure is provided for temperature calibration.

Accessories: A range of accessories is available, including wall-mounting adapters, interface modules for calibration, and various sensor protections.

Technical Support: Contact information for Delta Ohm srl is provided for further assistance.
