2.1 Overview
2.2 Description
Wherever the process pressure has to be transmitted electronically but a cable connection of the pressure sensor is
out of the question, the IIoT-capable measuring instrument model PEW-1xxx nds its application.
The fully welded sensor element absorbs the pressure and thus experiences a change in resistance of the measuring
bridge as a measure of the applied pressure.The measuring electronics convert the change in resistance into an
electronic signal, which is transmitted to a receiver via the radio module.
On the electronics, the temperature value in the instrument is registered and made available in the radio protocol.
The battery-operated radio transmission is achieved via LoRaWAN®based on LPWAN technology (low-power
wide-area network) to enable large transmission ranges and long battery life, or via Bluetooth®Low Energy.
The model PEW-1xxx meets all safety requirements of relevant standards and regulations for measuring the operating
pressure of pressure vessels as well as the requirements of the radio equipment directive for data communication.

The transmission of the measured pressure values to an IIoT platform is carried out at a preset sending interval.The
measurement and sending intervals, and also the alarm limits, for particular measured values can be congured over
the IIoT platform.
Using a mobile device with a local interface via Bluetooth®Low Energy, the instrument status (current measured value,
battery life, etc.) can also be queried on-site and the instrument can also be congured.
An update of the measured value only occurs in line with the set measuring rate! Until the next
measurement, the sensor transmits the last valid measured value.
2.3 Functional principle (model PEW-1000)
The model PEW-1000 uses the LoRaWAN®class A radio standard, which is designed for energy-saving operation.
The last registered measured value is, optionally, transmitted via Bluetooth®in “periodic advertising mode” at an
advertising interval of 1.25 s.
→ For details on the Bluetooth® connection, see chapter 3.8.2 “Bluetooth® Low Energy” and the additional
documentation “Special documentation for BLE communication specications, models PEW-1000 and PEW-1200”.
→ For details on the LoRaWAN®, see: https://lora-alliance.org
→ For details on the LoRaWAN®communication protocol, see “Special documentation for LoRaWAN®communication
specications, model PEW-1000”

■
Battery charge status in V
Example for downlink contents:
Conguration change (e.g. measuring rate, sending rate, alarm parameter etc.), which can be recognised by the system.
2.4 Functional principle (model PEW-1200)
The model PEW-1200 uses the Bluetooth®radio standard which is designed for energy-saving operation.
The measuring rate can be dened independently of the transmission rate. The model PEW-1200 can be congured
such that, on triggering of an alarm, the measuring rate is changed, see chapter 4.5 “Alarm description”.

Information
... points out useful tips, recommendations and information for ecient and trouble-free operation.
3.2 Intended use
The pressure sensor is used for wireless transmission of a pressure and temperature value.
This instrument is not permitted to be used in hazardous areas!
This pressure sensor is not suitable for applications with direct food contact.
The models PEW-1000 and PEW-1200 have been developed for use in non-hazardous media, i.e. for media of uid
group 2 in accordance with directive 2014/68/EU article 13. The use with hazardous media (uid group 1 in accordance
with 2014/68/EU article 13) is not allowed.
The pressure sensor must not be used in applications with unstable uids, especially hydrogen.
The remote monitoring of the process pressure via radio transmission is only suitable for non-critical and non-safety-
relevant applications.
The LoRaWAN®signal may only be used for mobile applications to a limited extent.This applies particularly
to high spreading factors.
The instrument has been designed and built solely for the intended use described here, and may only be used
accordingly.
The technical specications contained in these operating instructions must be observed. Improper handling or
operation of the instrument outside of its technical specications requires the instrument to be taken out of service
immediately and inspected by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
