In the present age of technology, the need of precision and optimum measurement is indispensable. Each day, companies invest in a great deal of effort and resources, just to get an inch closer to precision and accuracy. The business world today has come to depend on technology for a greater extent and hence it has given rise to the usage and utilization of process control instruments.

Process control instruments can be further grouped under two major categories, which are:

Temperature Measurement & Control

Temperature measurement and control instruments are necessary for separation and reaction processes and where it is essential to maintain a particular temperature for the life of the reaction or the process. Various sensor instruments are available which measures the slightest deviation in the temperature and helps you take the necessary steps to maintain a steady temperature.
There are various different sensor instruments available, but before making the choice, you must check the strengths and weaknesses of them, in order to make the profitable investment. Some sensors might get damaged ...
... in the due course of the reaction. They are therefore protected by the sheath or thermo well, which acts a physical and chemical barrier between the process and the process control instruments, thus shielding the instruments against any particular damage.

Flow Measurement & Control

Flow measurement and control is another important area of process control instruments. Flowing systems require energy - which is provided by pumps and compressors – and produces a pressure difference, which is the main driving force behind the flow. It is essential that flow control instruments should introduce a small flow resistance in a way that would not have drastic implications on the consumption of the energy by the process.
Some other flow sensors require straight pipes before and after the sensor itself, thus it limits the scope in which the design of the plant can be prepared. The flow sensors discussed thus far are for the clean fluids and special provisions are required for concentrated slurries and other process situations.
Types of Process Control Instruments

- Digit Process Indicator

- Data Logger

- Water Flow Meter

Here is a list of process control instruments which are essential to have at your center:

Tachometers, RPM / Speed Indicators, Ampere hour Meters, Digital Counters, Digital Timers, Humidity Indicators / Controllers, Conductivity Indicators / Controllers, pH and ORP Indicators / Controllers, Digital Temperature Indicators / Controllers, Process Indicators / Controllers, Calibrators, Flow Indicators / Controllers, Peak Load Indicators / Loggers, Production Display Boards, Data Loggers / Data Acquisition Systems, Digital Read, Out for Encoders and Clean Room Monitor.

All these instruments come really handy in the field of engineering and companies that have adopted engineering principles in its factory design.

The precision instruments as the humidity meter, humidity controller, and digital counter, are indispensible in this age of technological advancement as the accuracy of the readings are considered to be very crucial in the development of the product.
