GQ - Single-phase solid state relay, up to 90A

Zero crossing relay with antiparallel double SCR output is the most used solid state relay in industrial applications.

In fact, it can be used for resistive, inductive and capacity loads.

"Zero crossing" relay is energised when voltage meets the zero point and disenergised when current meets the zero point, depending on the signal control on the input circuit.

This relay has been designed to stand high-value transitory applications. When the relay has to stand high currents for a long period, it is necessary to grant a proper dissipation and an adequate electrical connection between relay terminals and the load.

Heatsinks, plug-in connectors, varistors, fuses, thermostats and fans, adhesive dissipating strips, are available as fittings.

GTS - Single-phase solid state relay, up to 120A

The insertion and disinsertion of an electrical load requires the use of a suitable switching device and protection that is safe and immune to interference.

Many industrial applications require the load to be activated with very short switching times in order to maintain accurate control.

The solution is to use solid-state relays. Gefran offers a range of solid state relay units, GTS, with current ratings between 10A and 120A and nominal voltages of 230Vac, 480Vac.

According to the type of load, there are Triac versions, and double SCR versions.

All models have been designed to guarantee continuous operation at the full current rating in an ambient temperature up to 40°C.

For less critical operations, it is possible to use the products at currents greater than their nominal rating (refer to the heat dissipation curves).

A range of accessories is available: fuses, fuse-holders and DIN rail connections.

GFX4IR - Power controller 4 PID loops for SWIR lamps up to 80kW

GFX4-IR is a four independent loop controller, designed to manage electrical power.

GFX4 is a compact unit bounding different technological elements like:

controller
solid state relay
current transformers
fuses-holders (option)
The final result is a cost saving in terms of space and cabling.

The GFX4-IR is managed by a microprocessor that independently controls the four control loops and also runs functions specifically designed to manage singlephase and 3-phase loads, with low and high temperature coefficient, medium and short wave infrared lamps, and transformer primary circuits.

The multiple activation methods are all software-configurable, and include:

Zero crossing with constant cycle time for conventional loads
Burst firing with variable cycle time for systems with low thermal inertia, medium wave IR lamps
Single cycle for short wave IR lamps with reduced flickering (half single cycle)
Phase angle control with current limit for short wave IR lamps, transformer primaries, with assignment of soft start up and soft stop down options with limitation of max. rms current.
GFX4IR runs complete diagnostics of current, voltage, and temperature levels:

Current

Total and partial interrupted load alarm
“Teach-in” function for self-learning of alarm threshold for interrupted load
SCR in short circuit alarm
Load in short circuit or in overcurrent alarm
Unbalanced 3-phase load alarm
Voltage

Phase loss in case of 3-phase configurations
Check of correct phase sequence alarm
Temperature

Overtemperature alarm
Various feedback functions in the absence of PID control have been developed for complete control of loads in all types of applications:

Voltage feedback (V) with current limit
Current feedback (I)
Power feedback with maximum power limit
Configuration is changed by setting simple parameters with a software tool that guides the user to a correct and safe configuration.

GFX4-IR dialogs with the operator terminals according to the most popular protocols: from the simple and efficient Modbus to (via a second optional fieldbus communication) the by-now indispensable Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP, Ethernet IP.

The product comes with a standard configuration that is simple and quick to modify, for example, to assign different functions to outputs.

Potentiometers position sensors

Potentiometers measure displacements and mechanical strokes. They are absolute sensors that maintain the detection of the stroke, and therefore of the position, even in the absence of a power supply. This makes them particularly suitable for installations on devices where setting the zero position is particularly complex. To allow the installation of these sensors on different types of industrial machinery, Gefran has several models of potentiometers, characterized by different mechanical features (linear or rotary, long or short strokes, exposed tracks, fixing by flanges or brackets, self-aligning joints).

Product category: Edge and center sensors

Magnetostrictive position sensors

Magnetostrictive sensors, or non-contact position transducers, allow to measure the position and displacement of moving mechanical parts. Magnetostrictive transducers are born as an evolution of linear position transmitters based on potentiometric technology. Thanks to the magnetostrictive technology that replaces the traditional mechanics composed of brushes sliding on a resistive track, the position detection is transferred to the primary magnetostrictive element without any mechanical contact, but through the field generated by a magnetic cursor that can be sliding or floating.
In this way, wearing problems have been eliminated, guaranteeing an almost unlimited life span. To adapt to the various application requirements, these sensors are available with different strokes, both with profile mechanics for external mounting by brackets and with stem mechanics for internal cylinder mounting. The outputs available are analog current/voltage, digital SSI and CANopen or PROFIBUS fieldbus.

Available with standardized mV/V output or an EEPROMModule to allow for higher mV/V-Output for better signal/noise ratio (to be used with special VDA-Amplfier).

High-grade steel for endless cycles and optional amplifer necessary.

Strain and force sensors - GE1029-A Tie-bar strain sensor with amplifier

The strain gauge sensor GE1029-A measure the surface-strain directly at the mounting location in the same quality as bonded strain gages.

The integrated variable digital amplifier amplifies the signal on the spot, avoiding EMC problems.

The sensor does not have to be recalibrated between remove and re-installation.

The press-on technology, developed by Sensormate AG, presses the strain gauges under the stainless protective film so strongly against the surface to be measured that frictional contact occurs.

The sensor is mounted using stainless steel straps, is non-destructive, very fast and simple.

For each tie-bar diameter outside tolerance of ± 2.5mm a different pair of steel straps is required.

The sensor can not be overloaded.

The GE1029-A sensors require a cyclic reset.

Strain and force sensors - SL76-VDA Strain link sensor with cariable digital amplifier

The strain link sensor SL76-VDA picks up surface-strain between the 2 mounting locations.

The strain occuring between the mounting areas is mechanically amplified inside of the sensor.

The integrated digital amplifier processes the signal on the spot avoiding EMC problems.

Thanks to the rugged design, these sensors are used in heavy industrial environment. They require a cyclical reset.
