Transducers for switchgears and electrical power and energy distribution networks

Tillquist Group AB has been producing and marketing acclaimed transducers since 1965. They are designed mainly for switchgears electric power and energy applications, and are available in a wide range, including everything from digital multi transducers to simple passive galvanic isolators. Suitable for DIN rail mounting, 19” rack solutions or customized versions.

Conversion of electrical quantities

Our transducers are available for the conversion of electrical quantities such as alternating voltage, direct voltage, alternating current, direct current, active power, reactive power, apparent power, frequency, power factor, tap changers, temperature, pressure and flow. They are available with analogue outputs, Modbus RTU, Profibus or Profinet.

Leading supplier of transducers

With over 50 years of experience in the industry, and excellent collaborations with customers and technology consultants, Tillquist is today a leading supplier of transducers.

Wide range of transducers

Our range includes the following products:

• Cos phi/phase angle- A transducer where the output signal is either a phase angle in degrees or proportional to cos phi. This range includes the LQT400, which is a configurable multi-transducer with 2 analogue outputs, and the LQT40A/S/F, which is a configurable multi-transducer for all electrical quantities
• Power - For active or reactive, or combined for both quantities. Available in enclosure for DIN rail mounting, and 19” rack and measure using the TDM principle
• Frequency – We offer several models in the frequency category. These convert a frequency into an analogue signal
• Configuration tools - Various tools for configuring transducers and digital panel instruments
• Multi-transducers – For measuring electrical quantities on a grid. They have either analogue or serial outputs. Available in several designs
• Resistance/tap changers – For measuring resistance of e.g. potentiometers, tap changers or PT100s for temperature measurement
• AC voltage– Available in several designs and used for alternating voltage
• DC voltage – For direct voltage
• DC current – For direct current with galvanic separation between input and output
• Temperature – Available in several variants of transducer for temperature measurement
• Accessories – We offer accessories such as I/O modules and shunts
