Indicator & Controller

Digital Indicator

Digital Indicators are flexible devices that can be used in many different fields such as industry and research and for a wide variety of measurement works. Digital indicators allow the user to view diverse parameters such as temperature, humidity, vibration, normalized signals, etc. Digital indicators with frame insertion are usually mounted on a panel together with other digital indicators or control systems. Digital indicators have a case so they can be used as mobile devices. Digital indicators with IP 65 protection can be used in harsh conditions. In addition to standard signal measurements and indications, digital indicators can also measure other physical quantities, such as temperature or force, using sensors directly connected to the indicator. The advantage is that programmed settings are stored, so other digital displays can use the same setting to save time, especially when different digital indicators should do the same work. Additionally, this function protects digital indicators against misuse.

Controller

The program controller employs an easy-to-read LCD along with navigation keys, thus greatly increasing the monitoring and operating capabilities. A ladder sequence function is including as standard. The short depth of the controller helps save instrument panel space. Program controller provides program patterns, and simultaneous monitoring of multiple PV events, multiple time events, and multiple alarm.

A temperature controller is a device that is used to control temperature. It does this by first measuring the temperature (process variable), it then compares it to the desired value (set value). The difference between these values is known as the error (Deviation). Temperature controllers use this error to decide how much heating or cooling is required to bring the process temperature back to the desired value. Once this calculation is complete the controller will produce an output signal that affects the change required. This output signal is known as the (manipulated value) and is normally connected to a heater, control valve, fan or some other "final control element" which actually injects or removes heat from the process.

The role of the temperature controller is to measure the temperature on the thermocouple, compare it to the setpoint and calculate the amount of time the heater should remain switched on to maintain a constant temperature.

Many factors change the amount of time that the heater needs to on, to maintain the process temperature. For example, the size of the heater, the size of the oven, the amount of insulation surrounding the oven and the ambient temperature will all change the rate at which the oven will heat up or cool down. Other factors such as the circulation of air within the oven, the humidity of the air.
