For high RH% and high temperature processes see IM-3. PPS body, wire mesh ﬁlter Probe and probe cable: min. -50°C (-58°F), max. 200ºC (392ºF) Probe connector: min. -40°C (-40°F), max. 85°C (185°F) HygroClip IM-1 Similar to IC-3, but with a short body, this probe is designed for full immersion in the process to be measured. Temperature limits: same as IC-3 HygroClip IM-3 Similar to the IC-3, this probe should be selected for use in processes that combine high humidity and moderate to high temperature such as pasta dryers, environmental chambers, etc. - Stainless steel body, wire mesh ﬁlter Temperature limits: same as IC-3 HygroClip IC-1 Similar to the IC-3, but with a short body, this probe can be installed well inside the process to be measured. The IC-1 is also used for measuring inside ducts with a small cross section. In both cases, the probe should be fully immersed in the environment to be measured (see installation below) PPS body, wire mesh ﬁlter Temperature limits: same as IC-3 HygroClip IE-3 Measurement in compressed air. This probe has a 1/2" NPT thread and can be used at pressures up to 50 bar/725 PSI.

The adapter is comprised of a compression ﬁtting and a 3'' ﬂange. The probe should be immersed as much as possible in the process to be measured, especially when temperature is not the same on both sides of the wall. IC-1 and IM-1 probes (short probe body): the probe and its cable should be fully immersed in the environment to be measured (leave the probe connector outside). In a duct of small cross section, install the probe axially. Attach the probe with a clip, a tie or a bracket at a well ventilated location (such as a vent). Do not install the probe through or against a wall, unless temperature is the same on both sides of the wall: insufﬁcient probe immersion will result both in a temperature and a humidity error.

Digital signal processing signiﬁcantly beneﬁts humidity and temperature measurement in the following key areas: 1.Measurement Accuracy The digital circuits used both in the HygroFlex and associated probe are inherently more stable and consistent than conventional analog circuits. Digital processing of the sensor signals by the probe also provides more scope and greater ﬂexibility when compensating sensor linearity and temperature coefﬁcient. The ROTRONIC HYGROMER™capacitive humidity sensor has always been the leader both in precision and stability. With the application of digital technology, sensor performance is now further improved. 2. Maintenance and Calibration Unique HygroClip®digital technology virtually eliminates downtime during maintenance. When it is time for a scheduled calibration, the interchangeable probe can be ‘hot swapped’ in seconds with a calibrated replacement probe. There is no need to remove the complete transmitter to a calibration laboratory and there is practically no interruption of the measurement data. The HygroClip probe can be directly calibrated while connected to the HygroFlex (requires the optional display and keypad), or it can be calibrated separately using either a PC or the HygroPalm The Digital Advantage portable calibrator. Calibration and sensor data are retained permanently within each HygroClip probe. Software-based calibration is both simple and precise; there are no hard-to- reach, hard-to-adjust potentiometers. Multiple calibration points can be selected across the full measuring range. On-site performance verification is equally easy. Each HygroFlex has a test connector for use with a portable HygroPalm calibrator. The HygroPalm can display the signals from the HygroFlex without interrupting operation and a comparison can be made with the readings of the probe connected to the HygroPalm. 3.Measurement of Dew-Point and other Parameters Digital technology makes it possible to obtain parameters such as dew-point or the mixing ratio with economical, versatile and easy-to-maintain instruments and probes. Comparing the HygroFlex to existing chilled mirror technology typical requirements and problems are eliminated: no sampling system is required in most applications, the uncertainty between dew and frost is eliminated, and there is no mirror that requires frequent cleaning.

Product Summary & Technical Data Humidity goes Digital ® Ordering A Hygroﬂex 2 or 3 Modiﬁcations reserved Rev. 08/05/02HTS Notes 1. Calibration device: this is a small chamber that seals tightly around the tip of the probe. Using one of the available calibration standards (such as EA35-SCS), a known humidity is generated inside the calibration device. Upon reaching equilibrium with the humidity standard, the probe can be adjusted to match the value of the standard. 2. Probe simulator: plugs on the HygroFlex in lieu of the HygroClip probe to provide known ﬁxed values for both humidity and temperature. This is useful when there is a requirement to validate the electronics of the HygroFlex. Notes 1. Output is jumper selectable and can easily be changed in the ﬁeld without any required calibration. The range of the output signal (for example 0…300°F) is not affected. 2. The range of all outputs (%RH, Temperature) can be changed using the Rotronic HW3 software. 3.
