The FH series combines advanced probe technology
with a robust design
- Digital HygroClip plug-in probe uses well proven, highly stable and durable sensors
- Probe operating range: 0-100%RH and -40...85°C (-40...185°F)
- Wall or duct (through wall) configuration
- Probe can be separated from electronics by up to 100m/300 ft
- 2-wire (loop powered) or 3-wire electronics
- Unique, cost effective installation procedure
- Fully interchangeable HygroClip is quickly replaced with no loss of accuracy and no calibration
FH series
The FH is an advanced series of low cost transmitters used to measure humidity and temperature in greenhouses, manufacturing areas, clean rooms, research laboratories and other industrial applications. Depending on the application, choose either 2-wire loop powered or 3-wire electronics. The linearized output signals (DC current or voltage) are directly compatible with remote displays, recorders, controllers or various data processing systems.
Installation
The FH series features a unique installation procedure widely accepted by contractors and installers. Here is how simple it is:
Units are factory calibrated. Base plate and electronics are shipped in an individual box for protection during shipment or storage.
- Hole is drilled in duct or wall to clear the probe (duct mount only). Base plate is mounted and wires are connected. Electronic module safety remains in original box.
- Since no electronics are invloved during the installation, the base plate can be wired safely during any phase of the contruction.
- After final construction, electronic module is just snapped into the base plate and secured.
The HygroClip
The HygroClip is digital humidity-temperature plug-in probe with two analog outputs and a one-wire digital interface. The HygroClip uses the well proven ROTRONIC HYGROMER capacitive humidity sensor and a 1/3 DIN precision RTD. Both sensors offer exceptional durability and stability in all kinds of environments. The HygroClip has an separate range or 0...100%RH and -40 ...85°C (-40...185°F). Digital signal processing withinh the HygroClip maintains accurate measurements over the entire operating range.
About maintenance
Whenever maintenance in needed, both the HygroClip and the modular design of the FH series offer the following unique benefits.
The HygroClip provides true, 100% interchangeability. Unlike products that just feature a plug-in / interchangeable sensor, the HygroClip can be replaced in seconds without any calibration and without any loss of accuracy. Inside the HygroClip, a non-volatile memory retains the calibration data, sensor characteristics, serial number, etc. Finally, if the transmitter electronics need to be replaced, the modular design of the FH series makes it a snap.
ROTRONIC offers easy-to-uses software and accessories for in-house calibration. If you do not wish to calibrate, or if the HygroClip needs replacement, use the unique HygroClip exchange program. This plan is supported by the ROTRONIC worldwide distribution network. The fully calibrated replacement HygroClip-R always contains a new humidity sensor and a brand new filter.
If your insdustry requires frequent calibrations, you may want to consider rotating a number of HygroClips between the transmitters that are installed and a service stock of calibrated probes.
Both during installation and during maintenance, the FH series saves time and money.
