Transmitters and regulators for humidity, temperature and CO2

Transmitters and regulators for humidity, temperature and CO2

Transmitters and regulators for humidity, temperature and CO2

Product catalog summary
Overview: This document details the specifications and options for the HD45 and HD46 series of transmitters, indicators, and controllers. These devices are designed to measure and control environmental parameters such as relative humidity, temperature, and CO2 levels, making them suitable for indoor air quality monitoring in environments like schools, hospitals, and workplaces.
Specifications:
  • Parameters Measured: Relative Humidity (RH), Ambient Temperature (T), Carbon Dioxide (CO2), Dew Point Temperature (DP).
  • Sensor Types: Capacitive sensor for RH, NTC sensor for temperature, and NDIR technology for CO2.
  • Accuracy: RH: ±2% (10-90% RH), Temperature: ±0.2°C, CO2: ±(50ppm+3% of measured value).
  • Outputs: Options include analog voltage output (0-10V), RS485 with MODBUS RTU protocol, and relay outputs.
  • Power Supply: 24Vac or 15-35Vdc.
Models and Options:
  • HD45 Series: Models available for humidity and temperature, temperature and CO2, and CO2 only. Options include analog output, RS485 output, relay output, and LCD display.
  • HD46 Series: Models available for humidity, temperature, and CO2. Options include analog output, RS485 output, relay output, LCD display, and keyboard.
  • Configuration: Instruments can be configured via PC using RS45 or RS45i cables. Models with RS485 output use MODBUS RTU protocol.
Applications: These instruments are used for managing conditioning plants and ventilation systems to ensure good air quality and energy savings, complying with ASHRAE and IMC regulations.
Technical Data:
  • Measuring Frequency: 1 sample every 3 seconds.
  • Storage Capacity: 2304 records with selectable storage intervals.
  • Response Time: RH: <20 sec, Temperature: <30 sec, CO2: <120 sec.
Installation and Configuration: The instruments are designed for easy installation with quick access to terminal block connections. Configuration can be done via PC or directly on the instrument for models with a keyboard.
Product Specifications and Options: The document outlines various models of transmitters, indicators, and regulators for measuring temperature, humidity, and CO2. Each model has specific features such as analogue outputs, relay outputs, RS485 outputs, and display options. The models are identified by codes like HD45 and HD46, with additional characters indicating specific features (e.g., 'V' for analogue output, 's' for RS485 output, 'r' for relay output, 'd' for display).
Ordering Codes: Examples of ordering codes are provided to illustrate the configuration of different models. For instance, the HD45 7BdVr model includes a transmitter, indicator, and regulator for temperature and CO2 with two analogue outputs and a configurable relay.
Accessories: The document lists accessories such as the deltaLog14 software for PC connection, calibrated replacement modules, and various connection cables (e.g., RS45 and RS45i). These accessories facilitate the configuration and data download from the instruments.
Compliance and Standards: The products comply with several safety and electromagnetic standards, including EN61000-4-2, EN61010-1, and EN55022 class B. These standards ensure the products' safety, electrostatic discharge resistance, and electromagnetic interference management.
Company Information: Delta Ohm srl, based in Italy, manufactures these instruments. They specialize in portable and bench-top instruments for various measurements, including temperature, humidity, pressure, and more.

The versions with relay allow to monitor the measured environmental parameters when the user-settable thresholds are exceeded. The activation of the control is highlighted by the LED indicators (only on models HD46 ... R). The operation of the relay is very versatile, having modes of activation above and below the threshold, and with single or double threshold modes. The thresholds are configurable by the user throughout the whole measurement range. The LCD display option allows instant viewing of all the measurements taken by the instrument. The model HD45 BVR is distinguished by the ability...
