Zirconia sensor
Product Description
1. Product principle：
Porous platinum (Pt) electrodes are sintered on both sides of the zirconia electrolyte (ZrO2 tube). At a certain temperature, when the oxygen concentration on both sides of the electrolyte is different, the oxygen molecules on the high concentration side (air) are adsorbed on the platinum electrode Combines with electrons (4e) to form oxygen ions O2-, which makes the electrode positively charged. O2- ions migrate through the oxygen ion vacancies in the electrolyte to the Pt electrode on the low oxygen concentration side to release electrons and convert them into oxygen molecules to make the electrode Negatively charged. In this way, a certain electromotive force is generated between the two electrodes. The zirconia electrolyte, Pt electrode and gases with different oxygen concentrations on both sides form an oxygen probe, which is a so-called zirconia concentration battery.（EmV）=0.0496Tln（0.2095/P1）±CmV）（If the output electromotive force E of the oxygen probe and the absolute temperature T of the measured gas can be measured, the oxygen partial pressure (concentration) P1 of the measured gas can be calculated.
2. Installation form：
Easy to install The probe is installed in a screw type. The user only needs to drill a hole and install a fixing nut or flange at the required installation site, screw the probe in, and then connect it to the wall-mounted oxygen analyzer with a specific cable To work. When the length of the probe exceeds 1 meter, it is best to install a fixing device inside the probe. It is best to have an angle of 15-20 degrees when installing.
3. Signal output form：
The electrical output form of zirconia analyzer is usually: analog current/voltage signal, MODBUS232/485 communication and Ethernet communication signal
4.Application cases：
1. CE-2D-JM ISG-C-JM Application of heating furnace for metallurgical stainless steel strip hot rolling process. When the oxygen probe is used, there are two ways to introduce the gas to be measured: direct insertion and sampling detection. The in-line type has a short response time, does not require a heater, has a simple structure, is small and portable, but requires simultaneous detection of the temperature of the gas being measured. Sampling detection type Because the temperature of the oxygen probe is controlled by the heater, the measurement accuracy is high and the work is reliable, but the response time depends on the gas flow rate.
Pressure Sensor
With extended functions, high IP protection level, flexible application A new generation of pressure sensor with digital display
Features：
- Flexible application through configurable outputs: analog, digital and IO-Link
- Able to withstand harsh environments – the highest IP protection level on the market (IP67, optional IP69K) and a temperature range of –40…+125 °C
- Additional diagnostic functions: provide running time, pressure peak counter and internal temperature trend information
- One-stop purchase of the same system from sensors to network modules and connectors
Product Description：
For high-use industrial equipment, it is very important to detect all its parameters and be able to evaluate them. For example, modern roller grinding, milling or turning centers, these equipment have hydraulic circuits for changing tools and workpieces. To ensure the correct clamping of the tool and the workpiece, the process pressure of each hydraulic circuit must be monitored.
Balluff new generation digital display pressure sensor perfectly realizes this purpose. The new generation products are equipped with IP67 protection as standard, and even ip69k options are available. In addition to this exclusive feature, these sensors also provide extended functions: the configurable output allows you to flexibly use the pressure sensor, and use its comprehensive diagnostic function for condition monitoring. The switchable output is controlled by IO link and can read the set switching point or analog value. You can also use IO link to detect and eliminate pressure peaks in the circuit when needed. All of these features help improve the uptime of the device.
Flow Sensors
Features：
- Can directly detect liquid media
- Integrated structure design, high protection level
- Screw-in or in-line form factor, depending on the flow or pipe diameter. The same system can be one-stop purchase from sensors to network modules and connectors
- M12 plug for easy integration
- LED digital tube or display screen directly displays the flow rate
- UL and CE certification
Product Description：
In the application process of industrial equipment, in addition to pressure and temperature, changes in flow are also important detection targets. The flow sensor from BALLUFF can help users use the switch function to monitor changes in the process fluid. For example, in cooling pumps and compressors.Balluff flow sensor has a strong shell and high IP protection, making it an ideal choice for harsh industrial environment. And can accurately detect the pipeline fluid changes, they can remind you to pay attention to the flow pump failure, clogged filter or leakage in the hose system. Or in machining centers, they constantly monitor the flow of cooling lubricants to protect and ensure the full life of the tool. When it comes to monitoring other water media, such as coolant, Balluff’s flow sensors also stand out, making them indispensable in a wide range of applications.
