Relative Humidity Transmitters

Product catalog summary
Overview: The document introduces the THR-370 and THR-340 series of humidity transmitters, designed for industrial processes. These devices utilize advanced capacitive sensors and psychrometric probes to measure and control humidity variables efficiently.
General Specifications: The transmitters operate within a range of 0-100% relative humidity (RH) and various temperature ranges, with outputs of 2 x 4-20 mA. They feature a Pt 100 temperature sensor, accuracy of 0.2%, and are housed in IP-65 rated enclosures. They comply with CE standards for emission, immunity, and electric safety.
Humidity Analyzers: These devices use a psychrometric system to calculate humidity variables such as relative and absolute humidity, dew point, and enthalpy. They offer outputs in mA or digital communication via RS-485 Modbus.
THR Series Models:
  • THR-370/RS: Designed for difficult access areas, featuring a separate sensor.
  • THR-370/CM: Suitable for chamber use, with a metallic IP-65 box.
  • THR-370/LE: Wall-mountable with a 2-meter sheath.
  • THR-370/AM: For domotic use in clean atmospheres, with an ABS box.
  • THR-370/PR: For high temperature and pressure processes, with a special RH sensor.
THR-340 Series:
  • THR-340/CM: An OEM model for general applications, featuring an IP-65 ABS box.
  • THR-340/PR: Designed for process applications, with a special RH sensor and process connection.
Psychrometric Units:
  • SHP-100: Provides direct outputs for dry and wet Pt 100 sensors.
  • THP-1000: A psychrometric analyzer that calculates various humidity parameters and offers configurable dual 4-20 mA outputs.
Accessories:
  • SPF-340 and SPF-370: Devices for forced aspiration to enhance measurement accuracy.
  • Proasis DAS-Win: A Windows-based data acquisition software for supervisory control and remote supervision.
