Performance Level 'c' - 4...20mA output
The ME Performance Level ‘c’ series of Gefran are
Pressure transmitters for use in high temperature environment.
The main characteristic of this series is the capability of
Measuring temperature of the media up to 752 F (400°C) such as high temperature engineered polymers.

The constructive principle is based on the hydraulic transmission
Of the pressure.
The fluid-filled system assures the temperature stability.
The physical measure is transformed in an electrical measure
by means of the strain-gauge technology.

MAIN FEATURES
• Pressure ranges from:0-250 to 0-30000 psi  / 0-17 to 0-2000 bar

AUTOZERO FUNCTION
All signal variations in the absence of pressure can be eliminated by using the Auto-zero function.
This function is activated by closing a magnetic contact located on the transmitter housing.
The procedure is permitted only with pressure at zero

The "IMPACT" (I) series of Gefran are pressure transmitters, without transmission fluid, for using in high temperature environment
(662°F or 350°C).

Medium pressure is transferred directly to the sensitive silicon element through a thick diaphragm.

The micro structure includes the measurement membrane and piezo resistors.

Strain is transduced by a micro-machined silicon structure (MEMS). The operating principle is piezo resistive.

The minimum deflection required by the sensitive element makes it possible to use very robust mechanics.

The process contact membrane can be up to 15 times thicker than the membrane used in traditional Melt sensors.

The Impact (I) series is the right choice for Mercury free, and for absolute absence of filling fluid, for use in food and medical application.

Superior wear resistance is suitable with filled polymers.

Use in combination with the MI-KO-SIS control system provides the solution for releveling as well: at every misalignment with the car stopped and doors open, the system automatically corrects the position and returns it to level.
 
Lastly, because the ADL300 has a high overload value (200% of nominal current for 10 seconds), it can manage high starting current without overheating the inverter.
Other info on the ADL300

The ADL300 series can be used in all applications with geared or gearless technology and has the most important industry certifications based on current European standards for lifts and escalators, such as EN81-1:1998 + Amendment A3.
 
With regard to safety, the entire ADL300 series has SIL 3 certification according to EN61800-5-2 for contactorless operation.
 
The inverter also has the CE and UL/Ulc marks for lifts, obtained under the Elevator Controls and Accessories (FQMW/FQMW7) program.
 
Noisy external contactors between inverter power supply phases and the motor are replaced with silent internal electronic switches. The ADL300 significantly reduces switching noise and is therefore suitable for silent installations.

The ADL300 can operate in systems with CANOpen communication, with both DS301 and DS417 (CANOpen Lift) profile, as well as with communication based on DCP protocol both in position (DCP4) and speed (DCP3).

 As a result, product warpage, distortion and reject rates are minimized.
For maximum product quality, the part can be isolated in an enclosed chamber with a vacuum atmosphere, to eliminate the effects of oxidation, but other treatment can require the supplement of chemical additives (protective gas)
Temperature regulation was also a key point: to optimize test phases of the treated material, the melting time had to be reduced as much as possible.
Traditional Vacuum Furnaces are large and powered by banks of electric heating elements: they require several hours to achieve and maintain temperature. In the induction furnace made by Linn, the temperature in the oven can rise from 650 degrees to 1100 degrees in 3/4 seconds!

ADV200 inverters have a high passband for the velocity and current controller, making them ideal for high-dynamic applications. 
Gefran’s system is completely integrated in the ADV200 series of drives for use with asynchronous or brushless motors, thereby eliminating the need for external control racks.

Control functions for line sections can be downloaded as standard applications in ADV200 inverters.
Using a control system integrated in the drive reduces system complexity and eliminates delays and noise when transmitting variables, typical of systems with separate drives and axis boards.

For a precise cut, the carriage must be in the right position and its velocity must be perfectly synchronized. Any difference in velocity generates imperfections in the cut, and may cause stretching or mechanical breakdowns: the flying shear control firmware is specifically designed to adjust the reciprocal position of the carriage and the pipe to be sheared.

The carriage velocity profile is set by an electronic cam based on line speed and shearing length.  
Positive and negative accelerations can be set with linear and sinusoidal profile in order to choose the best compromise between reducing the maximum torque required by the motor and the wear of mechanical parts.

The system is simple to commission because the GF-eXpress configurator lets you work on the system parameters of the inverter as well as on the specific parameters of the application.

Use of the Softscope digital oscilloscope with synchronous sampling (sample time 1 ms) also allows simultaneous run-time check of drive and application variables for optimization of the control system.
