(1): HF520 transmitter is not compatible with industrial metal probesOrdering Codes 
Notes:
- The HF53 can be ordered with both analog and digital interface (see "cable fittings" in the table).
- The enclosure of all models with optional display and keypad and/or with digital interface is designed to be installed in the horizontal position.
- The M16 cable grip is located at the bottom of the enclosure. The 1/2" conduit adapter in located on top of the enclosure.
- The factory default setting for the dew point calculation is frost point below freezing.
- The calculated parameter uses the same unit system (metric or English) as the temperature output.
- Custom range: be sure to clearly specify the desired range at the time of order. When a special range has been ordered, the letters ST, SC or S are used in column 4, 7 or 8 in the above table. These generic codes will be replaced with a specific code only for quantity and repeat orders.
- The probe used with the HF5 must be ordered separately. For technical information on the different probe models, refer to document E-M-HC2 Probes-V1.
- One (1) AC5005 mounting flange is included with the HF52 and HF53 duct mount transmitter.
|
The Rotronic HF55 measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F), depending on the probe.
