IMTRON, part of the GHM Group, has launched their Purely Analogue Signal Conditioning TSA modules that offer well-established methods for processing, filtering, amplifying and galvanically isolating sensor data in high quality.

The modules can convert nearly any analogue sensor signal into standards signals that can then be processed, for instance, in a control unit for data acquisition. In order to prevent damage to the system and guarantee high signal quality, inputs and outputs are galvanically from each other and the supply voltage and signals are filtered.


Offering test stand design for machine construction and the automotive industry, status monitoring of machines and systems, monitoring of wind turbines and actuation of servo valves, the Purely Analogue Signal Conditioning TSA modules offer the following advantages:

  • Cost reduction – signal condition and galvanically isolating amplifier in one device, a separator isolator is unnecessary
  • More signals – optional second output for integration into PLCs, displays

and end devices for data acquisition

  • High signal quality – flexible interference suppression with replaceable

filter modules

  • Velocity – limit frequencies of up to 30 kHz
  • Precision – high precision and long-term stability
  • From a single provider – modules available for most analogue sensor signals
  • Special requests – tailored solutions possible, even in small quantities
  • Service-friendly – plug-in connection terminals ensure easy installation and quick replacement
  • User-friendly
  • No software necessary – plug & play

A selection of TSA modules comprising standard, two channel, special modules and TSA PWR special modules for actuation of servo valves are available.

The Basic Configuration

The TSA modules are designed for a potential-free signal conversion and conditioning in automation and measuring technology. Each of the modules has 3-way isolation with

flexible interference suppression with plug-in filters. They are designed as Butterworth or Bessel filters of the fourth order. Other orders and filter characteristics can be

implemented upon request.

With potential isolation and filter characteristics, the modules are particularly well-suited for suppression of interfering influences in measuring and control circuits, for galvanic isolation of power and signal circuits, as well as for prevention of earth loops.

With a ripple of < 2 mVpp and a precision of 0.1 %, the modules are well suited for technical measurement applications.

The standard supply voltage is 24 V DC. An optional12 V version is also available. The modules have plug-in connections for simple connection. The standard module

width is 22.5 mm.

Customer-specific adaptations (e.g. measuring ranges, amplification factors, sensor feed) can be realised.

The IMTRON TSA modules are able to measure and record practically every measurable variable regardless of whether it involves the monitoring of slowly changing variables,such as temperature, or rapidly changing signals, such as speed or vibrations, all data is recorded with chronological synchronisation.

IMTRON’s extensive expertise in signal conditioning is well recognised. Their applications can apply to a test stand with several hundred channels or a laboratory measuring station with only a few channels. The diversified product assortment

offers optimal solutions in every area of application. The company also offers tailored solutions to meet customer requirements.

GHM Messtechnik South Africa is part of GHM Messtechnik GmbH, an amalgamation of globally renowned companies comprising: Greisinger Electronic, Honsberg Instruments, Martens Elektronik, Imtron, T & A Telemetry & Automation; Delta Ohm and Valco.
