Industrial Smart Pressure Transmitters 4-20mA, HART, RS485 Modbus

Industrial smart pressure transmitters are microprocessor-based high-performance transmitters. With flexible pressure calibration function. Instrument equipment commonly used in industrial process control can convert fluid or gas pressure into standard analog signals (such as 4-20mA) or digital signals (HART, RS485) and output them to the control system. Beyond 4–20 mA, HART and RS485 Modbus, pressure can also be reported over a CAN network — see our CAN bus pressure transducer with CANopen and custom CAN 2.0B output.

What Is a Density Meter? And Guide to Types

What Is a Density Meter? We are discussing industrial density meters here, not laboratory densitometers. Industrial density meters are devices specifically designed to measure fluid density, performing real-time online density detection and displaying data such as density and temperature. They also support outputs of 4-20 mA, 0-1000Hz, RS485 Modbus RTU, HART, and other signals, facilitating industrial process control.

Pressure Sensor Selection: Gauge Pressure vs. Sealed Gauge Pressure

Previously, we discussed the differences and relationships between Gauge Pressure and Absolute Pressure. Some users have noticed that when purchasing pressure transmitters, there’s also the option of choosing between sealed gauge pressure and gauge pressure. So, what is the relationship between these two, and how should we choose? Gauge, sealed-gauge and absolute references are all available on our CAN bus pressure transducer with CANopen output.

Hydrogen Flow Meters for Mass and Volume Flow

Hydrogen flow meters are widely used in hydrogen energy fields, such as hydrogen production, hydrogen storage and hydrogen fuel cells. Typically used to monitor volumetric flow, mass flow and usage of hydrogen to ensure proper system operation and optimize performance. Since the value of hydrogen is very high, custody transfer metering is also a very important feature of hydrogen flow measurement.

Sulfuric Acid Storage Tank Level Measurement

In industries such as chemical engineering, metallurgy, pharmaceuticals, electroplating, and sulfuric acid storage and transportation, sulfuric acid, as a basic raw material, is extremely corrosive. 98% concentrated sulfuric acid is viscous, fuming, and easily releases volatile acid mist. Under certain operating conditions, it is also accompanied by complex conditions such as high temperature and crystallization. Therefore, sulfuric acid storage tank level measurement places stringent requirements on the corrosion resistance, stability, and safety of the equipment. Based on our experience at S......

Case: Non-Contact Ultrasonic Flow Meter For Water

A clamp-on ultrasonic flow meter is an instrument that uses high-precision ultrasonic sensing technology to measure flow rate. It mainly consists of a host and a set of ultrasonic sensors. These sensors can be installed on the outer wall of the pipe without the pipe or shutting down the system, and they will not contaminate the medium in the pipe. The clamp-on ultrasonic flow meter measures the velocity and flow rate of fluids by utilizing the propagation characteristics of ultrasonic waves. It has advantages such as being non-invasive, highly accurate, and widely applicable. Custom Case A cli......
