1 Safety precautions
1.1 Appropriate use
The PS17 differential pressure transmitter is designed to measure differential pressure in
cleanrooms, machines, filter technology and heating, ventilation and air-conditioning
systems (HVAC). It is used to measure the differential pressure of non-aggressive, non-
combustible gases up to a pressure of 10 kPa in non-explosive environments.
Always observe the operating requirements indicated on the type label and the data sheet –
particularly the permissible supply voltage.
The device may only be handled as indicated in this manual. Modifications to the device are
prohibited. The manufacturer is not liable for damages caused by improper use or failure to
follow these instructions. Violations of this type render all warranty claims null and void.
Repairs should only be carried out by the manufacturer. The device may only be cleaned
from the outside with a damp cloth.
1.2 Warning symbols
The device has been designed and tested to ensure its safety. However, it may still be
dangerous if used inappropriately. Precautions must be taken to prevent the device being
used incorrectly by mistake. This device requires no maintenance. The device must be
installed by trained technical personnel.
The following warnings are used in this instruction manual:
WARNING
This warns you of a potential hazard that could lead to serious bodily injury up to and
including death if the corresponding instructions are not followed.
2 Storage and transportation
Do not close the pressure inlets during shipping. Changes in barometric pressure may
damage devices with low measurement ranges.
In addition, ensure that the device is stored at the correct temperature (see data sheet).
3 Disposal
The electronic components of the device contain environmentally hazardous materials and
materials that can be reused. The device must therefore be sent to a recycling plant when
you no longer wish to use it. Compliance with the environmental codes of your country is
essential.

4 Description of the device and its function
4.1 PS17 differential pressure transmitter
The PS17 is a stationary differential pressure transmitter used for recording positive and
negative differential pressures and converting them into electrical signals.
The device is designed for use in cleanrooms, machines, filter technology, and heating,
ventilation and air-conditioning systems (HVAC). It is used to measure the differential
pressure of non-aggressive, non-combustible gases up to a pressure of 10 kPa.
The device may only be used in the approved measurement range (see type label).
The piezoresistive pressure transmitter can be used to measure symmetrical or
asymmetrical measurement ranges.
4.2 Models
The device is available in different models:
- With a fixed measurement range or toggling between 4 different measurement ranges
- 3 supply connection options:
a. 24 VAC / DC (with reverse polarity protection)
b. 15.. 32 VDC (2-wire)
c. 24 VAC (with galvanic separation)
- 3 electrical connection options:
a. 2 cable glands M16
b. 1 cable gland M20 (not for version with relay)
c. 1 connector M12 (not for version with relay)
- Optional: 3½ digit display
- Optional: Contact point/relay (not for 2-wire, cable gland M20
or connector M12).
The time constants and output signal are default settings (see type label). However, these
settings can be configured.

4.5 Display (optional)
If your device has a display, the measurement range will be shown in Pa or kPa. The lower
line of the display shows the number of the selected measurement range.
When a device is switched on, information is displayed in the following order:
1. program version
2. final value of the selected measurement range (for approx. 1.5 seconds)
3. measured values
1
Output value (displays pressure in Pa and
kPa, root-extracted signal in %)
2
Number of the selected measurement range
“R” (with optional switchable measurement
ranges)
3
Display “r” for root-extracted output signal
4
Display “0” if zero-point calibration is in
progress

Planning device attachment
7100.006204 PS17 Instruction manual 808.04.19
5 Planning device attachment
You can mount the device on a top-hat rail or screw it to a wall.
Install the device with the pressure ports facing downwards so that any condensation in the
hoses does not run into the sensor.
Avoid mounting the device close to any sources of heat or radiation (e.g. heaters,
direct sunlight...) as this could result in measurement errors.
You can also use the STP file for planning, which you can download from our website:
https://www.halstrup-walcher.de/en/products/all/PS17.php
5.1 Mounting on a top-hat rail and dismantling
You can mount the device on a DIN rail (see assembly instructions).
- Please note the dimensions of the device when planning the installation (see drawing
in chapter 4.3 Control units and dimensions).
- Ensure there is adequate space for the pressure and power supply ports under the
device. Prevent the hoses from kinking in order to ensure stable measurements.
5.2 Screwing to the wall
You can fix the device to the wall using 2 screws (see assembly instructions).
- The drill holes must be prepared. The dimensions (78 mm) can also be found on the
back of the device.
- The device has oblong holes for plumb alignment.

5.3 Planning the pressure connection
You can connect the pressure to the device using the pressure ports.
- Use hoses with a 4- or 6-mm inner diameter.
- When connecting the pressure, use the following table to ensure that the sign of the
pressure (+ or -) is correctly connected.
Type of pressure
Connect pressure to
Example
Positive
overpressure
+ Input port
0 .. 1 kPa
Negative
overpressure
- Input port
0 .. - 500 Pa
(output value positive)
Differential pressure

lower pressure at - port
0 .. 125 Pa
e.g. via a primary element
(e.g. a measuring orifice)
200 Pa
- 300 Pa .. + 1 kPa
- Do not allow hoses to kink or sag.
- Avoid accumulating moisture in the hose.
- If moisture can be produced in the hose or at the measurement location, the pressure
sensor should be mounted above the measurement location. The hose must not sag
between the sensor and the measurement location.
- Do not perform a function test with compressed or breathable air. This would damage
devices with low measurement ranges.
- Please follow all the technical specifications relating to general conditions for
applications in the data sheet at: https://www.halstrup-
walcher.de/en/products/all/PS17.php

Provide electrical connection

6 Provide electrical connection
The electrical power supply is connected via the cable glands at the bottom of the device or
(optional) using an M12 connector.
The electricity supply may only be connected by trained professionals.
6.1 Prepare supply voltage via cable glands
For devices with cable glands, you can lead the cables through the housing to the terminals
for the supply voltage (see assembly instructions).
- Ensure that the supply voltage is correct for your model
- Use cables with wire diameters of 0.25 .. 1.5 mm2
- Observe the connection diagram located in the housing cover
- The terminals are located at the bottom left of the circuit board
(see chapter 4.4 Internal )
- Determine whether the digital zero-point calibration input is to be used and inform the
installation technician
- Always observe the operating requirements indicated on the type label and in the data
sheet –particularly the permissible supply voltage
- Provide the connections according to your desired supply voltage:
