Inverters for controlling variables in HVAC-R systems 

Good management of measurement and control of process variables in an HVAC system is essential because it provides technical benefits as well as considerable returns on investment. 
 
Accurate measurement, rapid response, efficiency, and advanced control are fundamental tasks of products with high technology content. They improve the Life Cycle Cost of systems and guarantee correct operation of the entire process. 
 
In an HVAC-R (Heat - Ventilation - Air - Conditioning & Refrigeration) system, good management of measurement and control of process variables is fundamental for economic sustainability and system efficiency. 
 
In this field, control valves (despite their known disadvantages) are still used to manage flows. Using these devices with a motor whose speed can’t be controlled and that always runs at 100% causes the valves and mechanical parts to age quickly, with consequent loss of system efficiency. 
Gefran’s model 650 – 1250 - 1350 PID temperature controllers, in format 48 x 48, 48 x 96 and 96x96mm (1/16th, 1/8th and 1/4 DIN) are full of advanced functions. 
 
FLEX-VIEW DISPLAY 
On Gefran’s new controllers, everything can be customized: cfaceplate color, display, operator messages, logo, and use of the bargraph (1250/1350). 
Attributes, such as, character size, black/white contrast, and the combination of different message colors, guarantees excellent readability even at a distance. 
 
EASY AND FAST SETUP 
There are three configuration methods: from keyboard in only 7 steps, from PC with our free to download GF_eXpress configurator software , and from the Zapper portable configurator.. 
 
SETPOINT PROGRAMMER 
The temperature profiles can be set in 12 steps, grouped and saved in 4 programs with trigger inputs and programmable event outputs. 
 
PREVENTIVE MAINTENANCE 
Outputs can be programmed to indicate when the actuators ( relay, ssr, IR lamps ) are close to the lifetime limits and maintenance is needed. 
 
ENERGY MONITOR 
The Energy Monitor function monitors the electrical consumption of the process and signals any faults.

The magnetic strain gauge sensor QE1008-W measure the surface-strain directly at the mounting location in the same quality as bonded strain gages. 
 
The magnetic 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 mounting of the sensor is non-destructive, very fast and simple. 
 
Direct measurement of surface strain 
Quick and non-destructive assembly with magnetic press-on technology 
High accuracy and linearity in tension and pressure (like bonded strain gauges) 
Ideal for use on presses, injection-moulding and die-casting machines 
Application on tie bars with a diameter of 45mm or higher and flat surfaces 
Dynamic applications 
Without amplifier (passive)
