Rosemount 400VP Contacting Conductivity Sensor

The high-performance Rosemount 400VP Contacting Conductivity Sensor is a sensor created to precisely detect the conductivity of liquids. It is intended for usage in a variety of industries, including the petrochemical, chemical, and power sectors. This sensor is well-liked among process engineers and plant managers because of its dependability, precision, and simplicity of installation.

The conductivity of a liquid is measured using a contacting method by the two-electrode Rosemount 400VP Contacting Conductivity Sensor. Two electrodes that are submerged in the liquid being measured make up the sensor. The electrodes are subjected to an electrical current, and the resistance to the current’s flow is measured. The liquid’s conductivity is then determined using Ohm’s Law.

The Rosemount 400VP Contacting Conductivity Sensor’s Variopol (VP) connector, which enables simple installation and sensor replacement, is one of its important characteristics. The sensor may be connected and disconnected from the device quickly and easily thanks to the bayonet-style VP connector. With this function, it is simple to change sensors in the field without interrupting the workflow.

The extensive range of measurement capabilities of the Rosemount 400VP Contacting Conductivity Sensor is another important characteristic. The sensor is appropriate for a variety of applications since it can measure conductivity in the range of 0.01 to 200,000 S/cm. The sensor can be used in corrosive situations because it is available in a range of materials, such as titanium, Hastelloy C-276, and 316L stainless steel.

Additionally, the Rosemount 400VP Contacting Conductivity Sensor is built for simple calibration and maintenance. The sensor’s straightforward construction makes cleaning and maintenance simple. Numerous standard solutions, such as potassium chloride and sodium chloride, can be used to calibrate the sensor. Additionally, the sensor has an integrated temperature sensor that enables temperature adjustment, enabling accurate results even amid temperature variations.

A high-performance sensor that is dependable, accurate, and simple to install and maintain is the Rosemount 400VP Contacting Conductivity Sensor. The sensor may be easily replaced thanks to its Variopol (VP) connection without having to stop the process. It is a popular alternative among process engineers and plant managers due to its wide range of measurement capabilities, flexible material selections, and simple calibration and maintenance.
