Temperature, Relative Humidity & Barometric Pressure Transmitter
ENVIROsense is an environmental temperature, relative humidity and, optionally, barometric pressure transmitter with standard RS485 Modbus-RTU output + analog output. Available with ISO/IEC 17025 Calibration Certificates.
Common applications:
• Meteorology/Renewable energies: sensor with conformal coating for protection against condensation, contaminants, and salt.
• HVAC/Indoor: cost-efficient for general indoor use.
• Clean Rooms/High performance: for indoor environments when high reliability and robustness are key factors
Options:
- Barometric pressure
- RS485
- RS485 Low voltage
- RAS485 + 0-1V or 0-5V or 0-10V
Calculated Quantities:
- Dew point
- Wet bulb temperature
- Absolute humidity
- Mixing ratio
- Specific enthalpy
- Water vapour partial pressure
- Specific humidity
- Frost point temperature
- Saturation vapor pressure above water
- Saturation vapor pressure above ice
Cables:
- CPM12-5.5: 5m cable with 5 pole M12 connector, open wires on other end. For RS485 Modbus-RTU output
- CPM12-5.10: 10m cable with 5 pole M12 connector, open wires on other end. For RS485 Modbus-RTU output
- CPM12-8.5: 5m cable with 8 pole M12 connector, open wires on other end. For RS485 Modbus-RTU + analog output
- CPM12-8.10: 10m cable with 8 pole M12 connector, open wires on other end. For RS485 Modbus-RTU + analog output
Cables for Configuring the transmitter:
- CP24B-5: Configuration cable built-in RS485/USB converter. 5-pole M12 connector on sensor side and A-type USB connector on PC side. For Versions with only RS485 Modbus-RTU output.
- CP24B-8: Configuration cable with built-in RS485/USB converter. 8-pole M12 connector on sensor side and A-type USB connector on PC side. For versions with additional analog output.
Solar Shields:
- HD9007A-1: 12-ring protection shield from solar radiation
- HD9007A-2: 16-ring protection shield from solar radiation
- HD9007T26.2: Adapter from Ø 26 to Ø 14 mm to fit the transmitter into the protection shield from solar radiations HD9007A-1 and HD9007A-2.
