Eliminating the wire using wireless transmitter is the perfect solution for rotating equipment. It establishes data collection between the transmitter and the gateway by reliable communication even though the dryer was rotating.
ISA100 wireless temperature and pressure transmitters with orifice plates allow:
- No cabling installations or maintenance.
- Small amount of hardware and simple equipment implementation means minimizing potential vandalism.
Caustic soda and hydrochloric acid, produced in electrolyzer plants, are fundamental materials used in varieties of industries; chemicals, pharmaceuticals, petrol-chemicals, pulp and papers, etc. Profit is the result of the effective production with minimized running / maintenance cost. Proper control of the process brings you stabilized quality of products with the vast operational profit.
- Temperature is monitored to maintain consistency of the viscous fiber entering the drum.
- Existing system requires manual temperature readings.
- Wired temperature measurement is not available because the tank is rotating.

Delayed Coker is a type of coker who's process consists of heating residual oil feed to its thermal cracking temperature in a furnace. The most important variable in industrial furnace control is temperature. Temperature is measured throughout the furnace in different zones and temperature effects the materials being manufactured and therefore must be precisely monitored to prevent deviations in quality of the final product.
Blending plays a key role in industries such as food, healthcare and chemicals etc. Temperature and vacuum measurements are very important in minimizing the moisture content to ensure the quality of the final product. Strictly maintaining them throughout the process ensures the final product yield.
Geothermal power plants create electricity from geothermal energy. These power plants are similar to other steam turbine station; however their heat source is that of the earth's core. The created steam is used to turn the turbine for the production of electricity. Technologies include Dry steam, Flash steam and Binary cycle power stations with Binary cycle being the most common geothermal plant in current production. In the process of geothermal power generation the facility needs to monitor various processes, as in this case steam line pressure sits in remote from control room's location.
A horizontal rotary miller used to grind the limestone rocks with metallic balls as grinding stones. This is used as the raw ingredient to produce cement powder. The temperature needs to be monitored in order to control the process and the quality of the final product. The user was using an induction temperature measurement based on a rail system that was very fragile and therefore unreliable.
Direct Reduction Iron (DRI) is one of the processes to reduce oxygen from iron oxide pellets for steel plant. More than 90% of DRI processes use heated LNG as process gas where PID control for temperature or interlock control is of vital importance.
One important risk to manage with regard to coal stacks is preventing fires due to spontaneous combustion.
- Wireless pressure and temperature monitoring.
- Repeater was set under the gateway.
- The maximum distance between the repeater and transmitters is approximately 500m.
In recent years, more field wireless devices have been used in hazardous areas. Meanwhile, in plants that are usually recognized as hazardous areas, there are numerous metallic tanks and pipes that easily shield or reflect radio waves, as discussed later, thus resulting in a poor environment for wireless communication.
The innovation of wireless technology increases the use of wireless communication in the industry. The introduction of wireless communication to plants, however, requires strict features such as robustness, real-time responsiveness, and low power consumption. This has restricted the use of wireless communication to limited applications such as data logging and device status monitoring that does not require strict real-time responsiveness and data arrival reliability in communication.
