Important points of choosing all types of control and measurement equipment

In general, the control system is a set of equipment that is used in order to achieve specific and defined conditions of quality, quantity and even desired and specific services.
The most widely used and important control systems in the industry include temperature control systems, pressure control systems, humidity control systems, speed control systems, fluid flow control, surface control systems, etc.
Control systems are divided into types of displays, test measurement equipment, sensors and actuators that interact with each other to form a control loop.
Control systems have different types in terms of efficiency and programmability, analog or digital, number of inputs and outputs, control mechanism, mechanical or electrical, etc.
Control systems are divided into electric, pneumatic (wind or compressed air), hydraulic (oil) and electronic types according to the power source.

Equipment related to the temperature parameter included

Thermometers and thermometers - transmitters - temperature calibrators - temperature sensors and temperature measurement sensors.
Thermometers are divided into two types: contact and laser.
Contact thermometers include digital, gas and thermoresistance thermometers.

Temperature measurement and control sensors include

Thermocouples, RTD thermo-resistance, thermistor, radiant (infrared sensitive) and thermostats

Thermostat

It is a device that is used to control the temperature of a system in a certain range as a direct or indirect function, whose function is mechanical or electrical.
In air conditioning systems, thermostats are divided into types of immersed, wall, wall, channel, etc. thermostats.
Thermostats are divided into different types in terms of installation location, type of function, temperature range, number of working stages and sensor type.

Pressure parameter related equipment

Analog or digital pressure gauges, absolute and differential pressures, calibrators, pressure sensors, pressure transmitters, manometers, manostats, regulators and pressure relief valves, etc.

Equipment related to liquid level parameters

Site Glass, ultrasonic, floating, diaphragm, vibration, vane, radar, capacitor and pressure level gauges, which according to the type of fluid, pressure, fluid temperature and other conditions such as fluid output and its multi-phase nature Level controls are used.

Flow meter and equipment related to flow measurement

A flow meter is a flow meter that measures the ratio of fluid passing through a certain cross-section in relation to time.
Flowmeters or flowmeters are divided into electromagnetic, ultrasonic, open channel, gear, Corialis, pitot, turbine, vortex, etc. types.

Solenoid valves

Solenoid valves are used to control the fluid movement or adjust the fluid flow rate according to the fluid phase, type of fluid and the system under control.
Solenoid valves are divided into several linear groups, single output, normally open, normally closed, two way, three way and two way angular, etc.
In terms of operation mechanism, solenoid valves are divided into direct types, with pilot function, without the need for pressure difference, and coaxial types.
One of the most important things when choosing solenoid valves is to pay attention to the size, type and temperature of the passing fluid as well as the working pressure of the system.

Actuator

A device that converts one form of energy (electrical, pneumatic, hydraulic, manual) into rotational or longitudinal movement; that this rotational or longitudinal force is used to move the control valve stem or the motor handle of the dampers, etc.

Warnings

Alarms or warning devices are equipment to inform operators of dangers, end of work, problems in the system, etc.; which are produced and supplied in audio, optical and electronic types.

Thickness gauges

There are equipments that measure the thickness of metals and non-metals such as glass, pottery, paper, paint, etc.
The most important use of thickness gauges in the air conditioning industry is to use them in periodic testing and obtaining standard approvals for hot water and steam boilers, because the thickness of the furnace, tube sheets and tubes get corroded over time.

Water hardness test kit

The amount of TDS (impurities and water solutes) and water hardness (calcium bicarbonate and magnesium bicarbonate) in all heating and cooling systems should be tested and controlled according to regular planning.
To improve this, equipment such as TDS meters and water hardness tester kits have been produced and provided.

Air flow meter and CFM meter

A CFM meter is used to measure the amount of air passing through a certain section.
In such a way that we place the CFM meter device in the air passage (channel valve, etc.) and multiply the number on the display of the device by the size of the desired section (channel valve or ...) and the air flow rate of the section We reach the target.
