DESCRIPTION :

Industrial pressure transmitters are sensors with electrical transmission output for remote indication of pressure. Process transmitters differentiate themselves from pressure sensors through their increased range of functionality.

They feature integrated displays, offer high measuring accuracies and freely scalable measuring ranges. Communication is via digital signals, and waterproof and explosion-proof certifications are available. Through connection to diaphragm seals, they are suitable for harshest operating conditions. Ideal for OEMs, process applications, water processing, and industrial pressure applications.

CLASSIFICATION :

Pressure transmitter types include gauge pressure, absolute pressure, and differential pressure. Gauge pressure refers to the pressure that is less than or greater than atmospheric pressure based on the atmosphere. Absolute pressure refers to the absolute zero pressure as the reference and is higher than absolute pressure. Differential pressure refers to the difference between two pressures.

According to the working principle of the Industrial pressure transmitters:

·         Strain Gauge Pressure Transducers

·         Capacitance Pressure Transducers

·         Potentiometric Pressure Transducers

·         Resonant Wire Pressure Transducers

Electrical Output of Pressure Transducers .Pressure transmitters are generally available with three types of electrical output. Millivolt, amplified voltage and 4-20mA. Below is a summary of the outputs and when they are best used.

APPLICATIONS :

Pressure transmitters are mainly used in the following areas:

1.     Petroleum, petrochemical, chemical. Matching with throttling devices to provide accurate flow measurement and control. Measures pressure and level in pipes and tanks.

2.     Electricity, city gas. And other companies and businesses require high stability and high precision measurement and other places.

3.     Pulp and papermaking are used in places that require chemical-resistant liquids and corrosion-resistant liquids.

4.     Steel, non-ferrous metals, and ceramics are used in furnace pressure measurement and other places that require high stability and high precision measurement. They are also used in places that require stable measurement under strict control (temperature, humidity, etc.).

5.     Machinery and shipbuilding, used to strictly control the place where high precision is required for stable measurement.
