Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit:

To guarantee sufficient protection during transport and storage, observe the following:
● Keep the original packaging for subsequent transportation.
● Devices/replacement parts should be returned in their original packaging.
● If the original packaging is no longer available, ensure that all shipments are properly
packaged to provide sufficient protection during transport. Siemens cannot assume
liability for any costs associated with transportation damages.
The packaging only provides limited protection against moisture and infiltration.
• Provide additional packaging as necessary.
Special conditions for storage and transportation of the device are listed in Technical data
(Page 37).

Introduction

About Siemens' Transducers
Note
This product is intended for use in industrial areas. Operation of this equipment in a
residential area may cause interference to several frequency based communications.
1.6 About Siemens' Transducers
The transducers operate in association with Siemens' ultrasonic level monitoring products by
converting electrical pulses that are provided by the transceiver into ultrasonic pulses. When
transmitted, these ultrasonic pulses reflect from the material surface and echo back to the
transducer. The echo is converted back to an electrical signal, and is interpreted by the
Siemens transceiver using our proven Sonic Intelligence™ algorithms.
The effective acoustical energy is emitted from the transducer face and radiated outward,
decreasing in amplitude at a rate inversely proportional to the square of the distance.
Maximum power is radiated axially (perpendicular) from the transducer face in a line referred
to as the axis of transmission. Where power is reduced by half (– 3 dB), a conical boundary
defining the sound beam, centered about the axis of transmission, is established. The
diametric measurement of the cone in degrees defines the beam angle. Impedance
matching techniques are used to optimize the transfer of power from the transducer into air
and vice versa.

1.6 About Siemens' Transducers
All transducers incorporate an integral temperature sensor that reports the air temperature at
the transducer to the transceiver. The connection is transparent, in that both the ultrasonic
and temperature components of the transducer use the same leads.

Safety Precautions
①
Suitable for use in a corrosive environment
②
Not suitable for use in a corrosive environment
2.1 Preconditions for use
Risk to personnel, system and environment can result from modifications to the device,
particularly in hazardous areas.
• Only carry out modifications that are described in the instructions for the device. Failure
to observe this requirement cancels the manufacturer's warranty and the product
approvals.
The ST-H transducer body is a two part design molded in PVDF or ETFE with internal parts
potted in epoxy. The joint between the upper and lower sections is not a hermetic seal. The
structural integrity of the transducer will be compromised if the joint is exposed to an
environment that attacks epoxy. As a result, the top section will separate from the main body
of the transducer.
For environments that are compatible with PVDF or ETFE but may degrade epoxy, the
transducer must be mounted through a flange or stub mount using the 2" thread on the lower
section of the transducer. The joint between upper and lower sections of the transducer must
be isolated from the corrosive environment.

WARNING
Use in hazardous area
2.2 Use in hazardous areas
If the top section separates from the main body of the transducer, live circuitry will be
exposed to the hazardous environment, increasing the risk of an explosion if volatile or
explosive dusts or gases are in sufficient concentration. A malfunction of the level system
may also occur, which may affect the process using the ultrasonic ranging system.
Persons who install, connect, commission, operate, and service the device in a hazardous
area must have the following specific qualifications:
● They are authorized, trained or instructed in operating and maintaining devices and
systems according to the safety regulations for electrical circuits, high pressures,
aggressive, and hazardous media.
● They are authorized, trained, or instructed in carrying out work on electrical circuits for
hazardous systems.
● They are trained or instructed in maintenance and use of appropriate safety equipment
according to the pertinent safety regulations.
Risk of explosion.
• Only use equipment that is approved for use in the intended hazardous area and
labelled accordingly.
• Don't use devices that have been operated outside the conditions secified for hazardous
areas. If you have used the device outside the conditions for hazardous areas
permanently make all Ex markings unrecognizable on the nameplate.
