tEmperature Sensor Medical Applications | Fluids

Temperature sensor medical applications can demand and require the ultimate in accurate and reliable monitoring of critical temperature measurement. Monitoring fluid temperature adds the complexity of protecting the temperature sensor from the fluid while not restricting its flow. Application examples include Hemodialysis, Polymerase Chain Reaction (PCR) thermal cyclers, and Sterilization of medical equipment. 

Hemodialysis is a process that uses a medical filtration device to remove waste and water from a person’s bloodstream. Multiple fluid temperature measurements are required including blood, dialysate, and disinfectant solution temperatures. These critical temperatures ensure the success of the process for the patient’s health and for the long-term use of the device itself. PCR thermal cyclers amplify or copy segments of DNA providing valuable diagnostic information for molecular biology and viruses. Precise temperature control is a key to heating DNA segments for amplification, with sensors allowing for real-time temperature measurement or system calibrations.

Sterilization of reusable medical equipment is vital in protecting patients from the transmission of dangerous infections. Water and detergent solutions are maintained at precise temperatures ensuring proper cleaning and disinfection.
