TC Type MA Chip Thermistors

Amphenol Advanced Sensors' biomedical chip thermistor assemblies are designed for use in applications involving both intermittent and continuous patient temperature monitoring. Repeatability and fast response are essential not only for the intermittent temperature requirements associated with oral and rectal fever measurements, but also with the continuous monitoring often necessary during induced-hypothermia and general anesthesia or when employed in the care of infants and premature babies. Intensive care units, along with recovery rooms, have also adopted patient temperature as part of their vital sign monitoring procedures. Temperature monitoring for skin surface, tympanic, esophageal, Foley catheters, and biofeedback applications has also improved due to the high stability and tight interchangeable tolerances designed into each Thermometrics’ biomedical assembly.

Although low in cost, these highly stable, precision thermochips provide the reliability, tight interchangeable tolerances, geometries, and fast response times that are often required. Thermometrics employs experienced applications engineers who welcome inquiries, whether for assistance or to help with your design requirements concerning new and existing applications.

Routine continuous patient temperature monitoring is now feasible by using the convenience of the patient’s skin site as an indicator of body temperature. The stainless steel housing used is suitable for both reusable and disposable applications while maintaining maximum patient comfort.

Designed for use in catheter assemblies, these sensors are available with nominal resistance values of 2,252 Ω, 3000 Ω, 5000 Ω, and 10,000 Ω at 77°F (25°C). Close monitoring of manufacturing processes allow Amphenol Advanced Sensors to maintain tight interchangeability tolerances with volume production.

Intermittent body temperature measurements are common practice in all phases of patient care. This assembly is ideally suited for the disposable cover oral and rectal fever thermometers in use today. It features rugged construction with tip-sensitive shaft assemblies.
