It is with simple operation, long serving life and easy to maintain for features, etc.
Product Description
The Dry-wet oxygen principle flue gas humidity transmitter is distinguished by its exceptional features designed to elevate its performance in humidity measurements. A standout attribute is the high-precision auto-compensation system for temperature, effectively neutralizing the impact of environmental temperature fluctuations. Complementing this is a meticulous pressure compensation function, ensuring the accuracy of humidity readings. Users benefit from the flexibility to set upper and lower limits for humidity, allowing analog output in the 4-20mA and 0-10V ranges with superior precision. The integrative design of the transmitter, complete with a built-in PID heat tracing function, not only simplifies installation and operation but also contributes to extending the analyzer's service life and overall stability, making it an excellent choice for humidity measurement applications.
Operating on the wet-dry oxygen principle with ceramic humidity sensing, the transmitter excels in providing precise humidity measurements. Its 4-bit LED display conveys essential information, facilitating user interaction. With a broad test range of 0 to 50/85% VOL or Kpa H2O, it accommodates diverse humidity levels. Exceptional accuracy, with deviations of less than ±2%FS, and repeatability of less than ±1%, ensures reliable performance. The swift response time of T90≤30 seconds enhances its efficiency. Offering versatile analog output options in the form of 4-20mA DC and 0-10V DC, the transmitter also provides a one-way programmable alarm output for Dry contact type, with a maximum load of 220VAC/2A. Communication ports, including RS232 (default) or RS485, support one or two-way communication with selectable baud rates of 4800, 9600, or 19200bps. The power supply range is AC100 to 240V at 50/60Hz. Operating in a sample gas temperature range of 0 to 170°C, the device is designed for sample gas pass-in, compatible with non-flammable and non-strongly corrosive gases with minimal dust. With an appearance size of 110mm×220mm×250mm (H×W×D), a service life exceeding 24 months under normal use conditions, and convenient wall-mounting options, this transmitter is a reliable solution for precise and stable humidity measurements.
