Keg systems are used for cleaning of kegs. They belong to the so-called secondary systems, because there is no direct contact with the food. The pressure of the cleaning agent must be precisely monitored.

The high-purity ceramic measuring cell  in conjunction with an EPDM seal provides high chemical resistance. This assures overload-free operation and long-term stability. With the high switch point accuracy (0.5%) of the two independent set and reset points at minimum hysteresis (0.5%), these vacuum resistant sensors of the PE series offer good value for money in peripheral processes.

In the food industry, in particular in pasteurisation and fermentation processes, precise temperature measurement is indispensable. The temperature sensors used must be calibrated on a regular basis, which is very time-consuming and expensive.

To reduce costs and increase process reliabilty, the TAD temperature sensor is now used in these processes.
Müşteriye sağladığı yararlar
The sensor with a redundant design has two different sensor elements, monitoring each other in the process. So, occurring drift is detected in time. Furthermore, if one element fails, the process can be continued with the second measuring element (backup function).

The efector m sensors of the type IGT241 replace the existing proximity switches.
Müşteriye sağladığı yararlar
With its 90 mm long housing (thread length 70 mm), IGT241 has been specially developed for this application as conventional sensors with a thread length of 50  mm are too short. Due to the use of adapted materials (high-grade stainless steel housing and fixing nuts, gold-plated contacts) and the certified resistance to cleaning agents which are common on the market (Ecolab certificate), this sensor is ideally suited for the cleaning processes which frequently occur in this area.

Fail-safe inductive sensors of category 4 and SIL3 directly detect the stainless steel cover (manway) without contact. A special counterpart is not necessary.

A special counterpart such as a magnet or  coded target is no longer necessary for the function of the fail-safe sensor. The fail-safe inductive sensor directly detects metals such as high-grade stainless steel or mild steel, i.e. materials that are used on the machine anyway.

The two high-precision and long-term stable measuring elements of the TAD temperature sensor ensure reliability and quality in the process. The temperature-proportional 4...20 mA signal enables processing via all common controllers. To ensure easy further processing the signal for the relevant temperature range is scalable. The diagnostic output warns in the event of "drift warning threshold reached" and ”drift alarm threshold reached”. ifm electronic warrants a reliable drift detection within the preset drift thresholds for a period of 5 years. The integrated ASEPTOFLEX adapter thread enables hygienic fitting to all common process adapters. The completely sealed housing guarantees protection rating IP 69 K. The selected design reduces build-up of dirt and can easily be cleaned all around.

AS-Interface has become the established standard in traditional mechanical engineering. As a manufacturer-independent standard for binary field bus communication it replaces the previous parallel wiring. The bus system is used for the connection of actuators and sensors of the lowest field level such as the ProcessLine field module of stainless steel.

The AS-i ProcessLine family provides completely new possibilities for bus wiring. The still commonly used cost-intensive large stainless steel control cabinets are becoming obsolete. Bus modules can be installed where they belong, i.e. near the  sensors and actuators.

Everywhere in the food industry valves are used for shutting off, monitoring and controlling. They are decisive components for the safety, accuracy and reliability of plants. In order to reliably fulfil this task, sensors on the actuators of the valves are required in order to transmit the current valve positions to the controller or process control system via common interfaces.
Geri dönüşüm
Conventionally, magnetic or inductive proximity switches assume this task. They signal end stops such as "open” or "closed” to the controller by means of a  switched signal. However, the detection of intermediate positions is of increasing interest. It allows the detection of cleaning cycles for rising stem valves as well as the visualisation of unintended operating states by means of continuous valve detection. This is the only way to meet the growing requirements of modern process visualisation.
Müşteriye sağladığı yararlar
The efector valvis was designed for feedback of the valve positions on rising stem valves with a stroke of up to 80 mm. The sensor is fitted over the valve spindle and continuously measures the stroke. Freely programmable switching outputs transmit the actual limits of travel to the controller. Quick installation of the adapter and easy switch point teaching by pressing a pushbutton reduce the set-up time. As a result of the optimum distribution of force at the interface from the sensor to the adapter this system is insensitive to mechanical stress such as vibration.

In industrial processes where liquids, air or gases are used, valves are needed for dosing and control. These valves are seldom operated manually. Pneumatic valve actuators are normally used for mechanical positioning. The valve position must be monitored electronically. On the one hand to provide a feedback to the controller when a certain position (e.g. "open" or "closed") is reached. On the other hand it is necessary to monitor the valves centrally.

The devices in the IND range contain two inductive sensors for "open / close" detection of an actuator movement by means of target pucks. The digital output  controls the solenoid valve for the pneumatic quarter-turn actuator. The AS-i connection allows direct connection to the yellow flat cable via an M12 insulation displacement connector. LEDs serve as switching status indicators for inputs and outputs.
Müşteriye sağladığı yararlar
By using state-of-the-art production technologies it has become possible to incorporate the latest AS-i technology with sensors and switching outputs in a space-saving housing. Mounting is effected using two screws on the quarter-turn actuators, standardised to VDI / VDE 3845. Combined periphery fault and communication error LED at the module provide the user with two important signals during set-up and operation. Two data bits for the first time allow separate evaluation of the "short circuit" and "wire break" situations on the output to generate even more targeted service information. The T modules can be addressed before mounting using the addressing unit via the M12 connector without voltage being applied. With the integrated display the modules can be addressed manually or automatically in the "Easy Startup" operating mode. All these features facilitate mounting, set-up and maintenance for the user and increase uptime of the whole AS-interface system.
