Sensors and Transducers

Industrial Instrumentation: Sensors, Transmitters and Transducers

Selecting an industrial sensor involves more than identifying the variable to be measured. Process conditions, required accuracy, mechanical and electrical connections, and signal integration must also be considered.

At Garma Electrónica, we work with specialist manufacturers including Fischer, FineTek, SCAIME, ATMI, Comet, EFE Sensor and Lorenz Messtechnik, among others, to provide industrial measurement and automation solutions.

Our catalogue covers continuous measurement, switching and detection, environmental monitoring, weighing, motion and process control. Specifications and approvals must be checked for each individual product.

Main Industrial Sensor Categories

Pressure Sensors and Transmitters

Solutions for measuring gauge, absolute or differential pressure, depending on the instrument. Applications include hydraulic and pneumatic systems, filtration and industrial processes. Key selection criteria include measuring range, permissible overpressure, wetted materials and output signal.

Level Sensors and Transmitters

Instruments for detecting or measuring liquid and bulk solid levels in tanks, silos and storage systems. Technology selection depends on the medium, vessel geometry, operating conditions and whether continuous measurement or point-level detection is required.

Load Cells and Industrial Weighing Systems

Components for industrial weighing, batching, load monitoring and force measurement. Rated capacity, mounting arrangement, side loads, environmental protection and signal conditioning are important selection criteria.

Temperature, Humidity, CO2 and Environmental Monitoring

Instruments for monitoring environmental and process conditions in industrial facilities, technical rooms and ventilation systems. Depending on the application, transmitters, controllers, data loggers or devices with digital communication interfaces may be required.

Flow, Conductivity, pH and Redox

Measurement solutions for fluids and process parameters. Chemical compatibility, operating range, installation conditions and maintenance requirements influence instrument selection.

Torque, Position and Motion

Static and rotary torque transducers, encoders, resolvers and displacement sensors for machinery, test benches and automation systems. Selection depends on measuring range, speed, accuracy, mechanical connections and electrical interfaces.

Machine Safety and Auxiliary Components

Our catalogue also includes safety switches and sensors, together with other components used in industrial machinery and processes. For safety-related applications, applicable standards, system architecture and the specifications of the exact device must be verified.

How to Select the Right Sensor or Transducer

Before requesting a quotation, it is useful to define the main technical requirements:

Signals, interfaces and certifications are examples of selection criteria and are not necessarily available on every product in the catalogue.

Industrial Applications

• Machine builders: measurement, detection and control of variables within industrial equipment.
• Process industries: monitoring pressure, temperature, level and flow.
• Weighing and batching: controlling quantities, loads and material handling processes.
• Industrial maintenance: sensor replacement, compatibility checks and signal adaptation.
• Engineering and test benches: instrumentation for force, torque, position and other measurements.

Technical Support and Industrial Sensor Replacement

Sometimes the main challenge is not finding a new sensor but identifying a suitable replacement for an existing device. This requires checking the original part number and its electrical, mechanical and process specifications.

If you have a datasheet, a photograph of the product nameplate or a wiring diagram, you can send it to us to help identify a suitable solution.
