## Type MA 

## Biomedical Chip NTC Thermistors 

Thermometrics 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 for 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 Sensor Assembly. 

Within our Type MA line of NTC Thermistors, we offer a complete line of standard sub-assemblies. Continuous research and development efforts within Thermometrics have resulted not only in these fieldproven designs, but in the development of our Unitherm Thermochip Thermistor, designed exclusively for biomedical applications in the range of 32°F to 122°F (0°C to 50°C). 

Although low in cost, these highly stable, precision thermochips provide the reliability, tight interchangeable tolerances, geometries, and fast response times that are often required in medical applications. 

Thermometrics employs experienced applications engineers who welcome inquiries, whether for assistance, or to help with your design requirements concerning new and existing applications. 

## Applications 

- Intermittent Patient Temperature Monitoring  - For oral and rectal fever measurements 

- Continuous Patient Temperature Monitoring  - During general anesthesia, induced hypothermia, and premature infant care 

- Vital Sign Monitoring  - For Intensive Care Units (ICU) and recovery rooms 

- Temperature Monitoring  - For skin surface, tympanic, esophageal, foley catheters, and biofeedback

## Type MA Specifications 

## MA100 

## MA300 

Designed for use in catheter assemblies, these sensors are available with nominal resistance values of 2252, 3000, 5000, and 10,000 Ω at 77°F (25°C). 

Close monitoring of manufacturing processes allow Thermometrics to maintain tight interchangeability tolerances with volume production. 

Typical design parameters are represented in Assembly Type table. 

- 0.030 in (0.76 mm) (10 K Ω only) and 0.050 in (1.27mm) diameters available with kapton sleeve only. 

- 0.070 in (1.78 mm) diameter normally supplied with molded plastic tip. 

## MA200 

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 exhibiting resistance values of 2252, 3000, 5000, and 10,000 Ω at 77°F (25°C). Refer to Assembly Type table for typical design parameters. 

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. Nominal resistance values of 2252, 3000, 5000, and 10,000 Ω at 77°F (25°C) are available. Refer to Assembly Type table for typical design parameters.
