PRESSURE TRANSMITTER
A pressure transmitter or pressure sensor is a device that measures pressure in a liquid, fluid, or gas, or level of industrial liquids and gases. Transmitter use to measure pressure in different processes. Pressure transmitters are divided into three types:
Absolute Transmitter:
Absolute transmitter takes vacuum pressure as its base and then measures process pressure.
Gauge Transmitter:
This type measures process pressure with the location’s atmospheric pressure as a base.
Differential Transmitter:
When sensing units are introduced to multiple pressures as inputs, differential transmitters measure the differences between the various pressures. Then it’s transducing that pressure into an analog electrical signal.
TEMPARATURE TRANSMITTER
A Temperature Transmitter is a device that converts the signal produced by a temperature sensor into a standard instrumentation signal representing a process variable temperature being measured and controlled. The most common transmitter instrumentation output signal is 4 to 20 mA.
The two most common temperature sensors used are the thermocouple and the Resistance Temperature Detector (RTD).
The thermocouple produces a change in voltage with a temperature change. Thermocouples have only two wires. An RTD produces a change in resistance with a temperature change. Unlike a thermocouple that has only two leads, an RTD can have two, three, or four leads.
LEVEL TRANSMITTER
Level measurement transmitter are used in a myriad of applications that require level measurement within containers or tanks. These transmitters often find their application in material handling, food and beverage, power, chemical, and water treatment industries.
- Float Level Transmitters
- Buoy Level Transmitter
- Radar Level Transmitters
- Ultrasonic Level Transmitter
- Capacitance Level Transmitters
- Magnetic Level Meters
- Hydrostatic Level Transmitters
FLOWTRANSMITTER
A flow meter (or a flow sensor) is an instrument that is used to indicate the amount of liquid, gas, or vapor moving through a pipe or conduit by measuring linear, non-linear, mass, or volumetric flow rates. Since flow control is often essential, measuring the flow of liquids and gasses is a critical need for many industrial applications – and there are many different types of flow meters that can be utilized depending on the nature of the application.
- Differential Pressure Flow Meters
- Orifice Flow Meters
- Pitot Tube Flow Meter
- Ultrasonic Level Transmitter
- Positive Displacement Flow Meters
