What is an IP rating? IP65-IP67-IP68

When purchasing pressure transmitters or flow meters, the sales engineer will usually confirm with you what IP rating you need: IP65, IP67, or IP68? This explanation aims to help you understand the details of IP ratings. Next time you purchase electrical equipment, you’ll know which IP rating to choose.

Absolute Pressure Transmitters: Product List and Guide

What is Absolute Pressure Transmitter? Absolute pressure transmitters are sensors that measure pressure using absolute vacuum (0 bar) as a reference. They convert the sensed physical pressure value into a standardized electrical signal, such as 4-20 mA or 0-10 V, for processing by control systems or monitoring equipment. For absolute pressure on a digital bus, see our CAN bus pressure transducer with CANopen and custom CAN 2.0B output. They are often called “industrial barometers” or “technical barometers” because they can measure true, absolute pressure unaffected by e......

Gas Measurements: Normal Conditions vs Standard Conditions

In gas flow measurement and control, it is crucial to distinguish between Normal Conditions and Standard Conditions. This is primarily because the volume of gas changes with temperature and pressure. Different standards will result in different measured gas values. This is somewhat similar to the difference between “SCFM (Standard CFM) and ACFM (Actual CFM)“.

Thermal Mass Flow Meter Correction Factor Guide

Thermal Mass Flow Meters and thermal mass flow controllers are suitable for most gaseous media. If a gas mass flow controller or thermal mass flow meter is factory-calibrated for one gas, but you want to switch to another, then a gas correction factor (GCF) is needed.

Analog Gas Flow Meters | Types and Product List

Analog gas flow meters specifically refer to a type of flow meter that outputs analog signals. The main function of a flow meter is to measure volumetric flow rate or mass flow rate and convert it into an electrical signal output, facilitating flow monitoring and control. There are four types of flow meter signal outputs: analog signal output, frequency signal output, digital signal output, and switch signal output.

Magnetic Float Level Gauge: Working Principle and Types

The Magnetic Float Level Gauge continuously measures the liquid level in a tank based on the principles of buoyancy and magnetic coupling. It indicates changes in liquid level by utilizing the influence of a magnet on nearby magnets; this mechanical structure is simple yet highly effective. Its simple structure provides fast and stable liquid level information. Furthermore, when equipped with an electronic transmitter, it can be used for continuous monitoring and control of liquid levels.
