Humidity, Dew Point and Temperature transmitters - H3 and H5 series

Product catalog summary
Overview: The document describes the H3 and H5 transmitters, which utilize a highly accurate condensation-resistant capacitive sensor integrated into a silicon microchip. This technology ensures precise process measurements, reliability, and long-term stability. The transmitters are capable of calculating the Dew Point using integrated humidity and temperature sensors.
Specifications:
  • Environmental Limits: -30 to +90°C
  • Stability: Long-term drift of less than 0.5 RH% per year
  • Outputs: Two isolated analogue outputs for Relative Humidity (RH), Temperature (T), Dew Point (DP), and Temperature-Dew Point difference (∆T)
  • Alarm: Programmable relay output for UR, T, DP, ∆T
  • Real Time Clock (RTC) for event tracing and data storage
  • Serial Communications: RS485 Modbus RTU for digital retransmission and PC configuration
  • Enclosure Rating: IP66
  • ISO 9001 Certified
Hardware and Functions: The transmitters can be wall, duct, or remote sensor mounted. They feature a painted aluminum housing rated IP66 for industrial applications. The H3 model measures humidity and temperature, while the H5 model calculates the dew point and temperature difference. Options include alarms, event tracing, and data logging.
Communication and Interfaces: The transmitters support Modbus Protocol RS485 Serial Communications. Ascon offers Gateway Manager modules for fieldbus connections, including Profibus, DeviceNet, CANopen, and Ethernet with ModbusTCP protocol.
Alarms and Data Logging: The H5 model can configure up to 5 alarms, which can be combined with system measurements. Alarms can be configured as minimum or maximum, absolute, deviation, or band threshold. Event details and data logging are stored using the internal RTC.
Accuracy and Calibration: The transmitters are factory calibrated, and no further calibration is needed after replacing the Humi-chip sensor. Humidity and temperature measurements can be aligned using a reference transmitter.
Applications: Suitable for artificial snow making, air conditioning, and ventilation in pharmaceutical industries, as well as storerooms for ripening and preserving fruits, vegetables, meat, and cheese.
Technical Data:
  • Humidity Range: 0.0 to 100.0% RH
  • Temperature Range: -30.0 to +70.0°C
  • Accuracy: 1.8% between 10 to 90% RH
  • Output Types: 4 to 20 mA, 0 to 10 V, 0 to 1 V
  • Isolation: Galvanic isolation of each output: 500 Vdc/1 min
Mounting and Dimensions: The document provides detailed dimensions and mounting options for wall, duct, and remote sensor installations.
Ordering Information: The document includes ordering codes for different configurations, including probe material, filter type, serial port options, and analogue outputs.
