Thick film conductivity sensor serves single use applications

Equipped with four electrodes and four Pt/Ni wires, the latest thick-film conductivity sensor from Innovative Sensor Technology IST, the LFS1505 is small enough to fit into small handheld measurement devices. 

It is suitable for single-use applications and has fast, accurate response times. It is resistant to various chemicals and can be customised to an application from smaller order quantities to volume manufacturing.

The LFS1505 conductivity sensor is suitable for handheld devices in medical technology where single-use sensors are required, for example autoclaving, but it can also be used in wider applications including water treatment and quality monitoring over fuel cell applications and to prevent calcification in white goods and kitchen appliances.

The low cost conductivity is a standard product in the company’s portfolio of conductivity sensors with an on-board temperature sensor. It has been developed for use where temperature measurement is already included and only a single-parameter component to measure conductivity is required. 

The LFS1505 is a standard ‘off-the shelf’ sensor, but it can also be developed to fit application-specific requirements within a short development and production time, added IST.

The sensor’s conductivity range is from 1000 μS/cm to 100.000 mS/cm (typical cell constant of 0.66 cm-1. It operates in a wide temperature range from -30 to +100 degrees C. 

The chip measures 14.9 x 5.5 x 0.65mm and the four wires’ dimensions are 0.2mm diameter and 20mm long.

IST’s conductivity sensors are a used in applications ranging from water treatment and quality monitoring to leak detection in cooling & heat exchangers and condensers, to chemical processing, pharmaceutical and medical applications, food and beverage industries, and analytical laboratories.
