stable dew point monitoring in industrial applications. The newly
developed sensor features improved signal and stability in demanding
industrial applications.
It’s designed for OEM applications in desiccant and refrigeration dryers.
The measured dew point is output via the loop-powered 4 ... 20 mA
signal. Sensor parameters such as analogue output scaling, physical
units, can be set e factory.
4 Features

•Measures dew points down to –50ºC Td
•2-wire loop powered sensor or 3-wire
•Modbus/RTU signal output (model depending)
•IP65 casing provides robust protection in rough industrial
environment
•Very fast response time ensures safe and relia-ble indication
whenever dew points are out of valid ranges
•Can be installed directly into dryers through G 1/2” thread
•High accuracy of 1 … 2ºC Td dew point

Modbus output (S2 7-8 and S2 7-9)
8.2 Byte ordering and byte sequencing
In the response message that the device returns to the master:
•Function code: 03
•Byte order (32-bit data): MID-LITTLE-ENDIAN.
To properly decode the 4-byte float and unsigned integer data in
the response message, the master must change the byte order
from MID-LITTLE-ENDIAN to the order that it is using (LITTLE-
ENDIAN or BIG-ENDIAN).
Byte sequencing of byte orders:
Byte order Byte sequencing (HEX) Example
MID-LITTLE-ENDIAN
(Read from the device)
A B C D 0 0A 11 42 C5
LITTLE-ENDIAN B A D C 0 11 0A C5 42
BIG-ENDIAN C D A B 0 42 C5 0A 11
8.3 Interpretation of system status
The device provides the device statuses via Modbus as well. The 32-bit
data information is read as single bits. The meanings of these bits are
described as follows.
Bit Description
2Dew point over range
3 Temperature over range
6 calibration over due
7 EEPROM broken
8 Dew point sensor broken

Installation
9 Installation
Before installing the sensor, please make sure that all components listed
below are included in your package.
Qty Description Item No.
1 Sensor Model specific
(See section 9.3 for details.)
1 2 m cable with M8 connector No P/N
1 Instruction manual No P/N
1 Calibration certificate No P/N
9.1 Installation requirements
The flowing air or gas must pass the sensor tip for a proper
measurement. This can be realized with a measurement chamber. For a
installation without measuring chamber you need to concern the
installation depth which is described in the ne t chapter.
9.2 Installation procedure
The following steps e plain the procedure of an appropriate installation.
Installation of the sensor with measurement chamber
1. Connect the sensor with
the measurement
chamber.
2. Connect the sensor and
the measurement
chamber with the fast
connector.
14 S217

Installation
Installation of the sensor without measurement chamber
•Install the sensor only if
the system is
pressureless.
•Not less than 1/3 of the
sensor tip should be inside
of the pipe. For this please
check the size of the
nozzle.
•The inner thread must be
G 1/2”.
Remarks
Please install the sensor only
in the recommended area
like you can see in the
picture. A upside down
installation is not permitted.
Please consider that the
distance to the vertical level
must be >30°.
Removal of the sensor
To remove the sensor unscrew the sensor from the measurement
chamber or from the nozzle. Please observe that the system is
pressureless when the sensor is removed.

Calibration
10 Calibration
The sensor is calibrated e work. The e act calibration date is printed on
the certificate which is supplied together with the sensor. The accuracy of
the sensor is regulated by the on site conditions, parameters like oil,
high humidity or other impurities can affect the calibration and
furthermore the accuracy. However we recommend to calibrate the
instrument at least once per year. The calibration is e cluded from the
instruments warranty. For this please contact the manufacturer.
11 Maintenance
Please observe from time to time the sinter cap. If it appears to be
dirty, it is recommended to replace it for this please contact the
manufacturer.
TTENTION!
Contaminated filters can lead to longer response
time and to wrong measurements.
12 Disposal or waste
Electronic devices are recyclable material and do not
belong in the household waste.
The sensor, the accessories and its packings must be
disposed according to your local statutory requirements.
The dispose can also be carried by the manufacturer of the
product, for this please contact the manufacturer.
