The advanced digital temperature controller is a device that offers accuracy in temperature and enables to maintain a moderate climate and provides precision in temperature. Nowadays, it helps many industries, offices, hospitals, and other places where temperature fluctuations can occur.
The digital temperature controller manufacturer has advanced its technology by introducing innovative functions such as an Autotune PID feature. These types of equipment continuously show the temperature of the area. Moreover, it has an automatic process that keeps all the changes under control and turns off the heater when there is a high temperature.
Moreover, it has a sensor that performs as per the signals sent and monitor all the changes. This controller can control the temperature using both the cooling and heating portion of the air conditioner to reach a moderate temperature. Also, it maintains a temperature as tight as +/- 1°F of the desired set point.
Further, it allows full access and control from the enclosure’s ambient side by mounting through the enclosure wall. You can even attach these controllers remotely to a nearby control panel if desired. The remote-mount thermocouple can be foxed anywhere within the field, and it is beneficial where the hot spot within the arena is concerned. The digital temperature controller is accessible with RS-232 output (#DTC-R232), enabling it to control the cooling system tenuously through an RS-232 connection.
Digital temperature controller circuit and working
There are different components in the Digital temperature controller circuit, such as
- The circuit has around microcontroller PIC16F877A (IC1). It is the heart of the controller with high performance, low-power, and CMOS 8-bit microcontroller. It encompasses 256-byte EEPROM, 8kB Flash memory, 33 input/output (I/O) pins, 368-byte RAM, three timers, watchdog timer with its on-chip crystal oscillator for reliable operation, 10-bit 8-channel analog-to-digital converter (ADC), synchronous I2C interface, and watchdog timer with its on-chip crystal oscillator for reliable operation.
- The circuit has a precision thermocouple amplifier AD8495 (IC2).
- It has a K-type thermocouple (connected at CON3), 16×2 LCD (LCD1), single-changeover relay (RL1). The K-type thermocouple is used for direct measurements of up to 1000ºC temperature. Further, it contains two materials from the junctions are Chromel (Ni-Cr) and Alumel (Ni-Al). It is one of the most popular general-purpose thermocouples at a low cost.
- There are two types of temperature sensors used to measure temperature. The first is direct temperature-measurement systems for up to 1000ºC, and the second is indirect temperature-measurement systems for greater temperature ranges, where the high temperature may damage the sensor physically.
- Software compiled using Hi-Tech compiler and MPLAB to generate hex code with the ‘C’ language program. It has a suitable programmer with a configuration bit set, which produces hex code that is burnt in a microcontroller.
- Construction and testing are also there in the controller with an actual-size, single-side PCB for the digital temperature controller. It carefully assembles the circuit on a PCB to minimize assembly errors, double-check for any overlooked error to save time.
There is some hardware implementation of the Digital Temperature Controller. This hardware helps to execute the work properly when to connect and link together in a specific pattern. The hardware includes
- Voltage regulator
- Seven segment temperature display
All of this hardware has some specific implementations. It has a few complex deployments, and all the consequences are different in every situation and scenario. These controllers can be mounted in various places to control the temperature, such as:
- Medical houses and industries use these controllers to keep the medicians, liquids, and tablets at a moderate temperature as required. It is a saver to use as every medician has a specific temperature under which it is kept. So, places where there is very high or low temperature mostly use these controllers to maintain atmospheric conditions.
- Industrial houses use the temperature controller for regulating the same. They use computer systems and machines that increase in temperature with everyday use.
- Industrial houses use a controller for sensitive usages like Nuclear energy systems managing homes.
For all types of vision of the microcontroller, the temperature of the controller is best. It helps appropriately functioning and manages temperature more accurately in several sensitive ground temperature plays an important role. These controllers have changed the scenario of these places positively.
Moreover, these digital temperature controllers are not complicated as people think and turn out to be a perfect alternative for thermostats and analog systems. Temperature controller has played an important role in making every aspect of life better. Additionally, it has helped these sectors in unexpected ways possible.
