The AquaMetrix Model ES-5 Series Conductivity Sensors are used in processes where conventional contacting sensors may become fouled or corroded. These probes are unique in the marketplace. They are loop-powered and provide direct 4-20mA output. Each sensor comes standard with a Pt100 RTD temperature device, which provides automatic temperature compensation to 77°F (25°C).
The ES-5 Series are equipped with 1.5" MNPT threads on both ends so that they can be mounted for in-flow applications or submersion mounted in tanks or open vessels.
Toroidal conductivity sensors are made up of two0wire wound toroids encapsulated in a potting compound and encased in a plastic body. One toroid acts as a transmitters and the other as a receiver. An electric current is induced between the toroids through the process solution. This current is directly proportional to the conductivity of the solution.

Here's how some of our customers used this product.
Determining the Strength of Acids by Measuring Conductivity
The Background: A processing plant needs to monitor the strength of powerful acids used as cleaning agents.
The Problem: Typical pH probes are generally designed for measuring between 2 and 12 pH. Outside of that range, accuracy is greatly diminished. To account for this, it is common to measure the concentration of the acid or base with a conductivity meter rather than measuring the pH level. One problem with this is that standard contacting conductivity probes are likely unable to handle the corrosive nature of strong acid and bases.
The Solution: The AquaMetrix ES-5 is a toroidal conductivity sensor that measures conductivity by inducing a current, a technology that does not require contact with the sample making it ideal for highly corrosive environments. The ES-5 will provide accurate conductivity readings as a way to determine the concentration of an acid or base.
