Within designated ranges, Thermistor Probes offer higher accuracy and greater long-term dependability than thermocouples. Providing regulated excitation current, the Model 10A15-8 can condition up to eight independent temperature signals from many 3-wire, dual-thermistor-bead probes. A variety of suitable fast-response sensors is available in the Daytronic Series 700 Thermistor Temperature Probes (see the latest Daytronic Transducers Catalog).

Like the Models 10A9-8C and 10A10-4, the Model 10A15-8 provides "absolute" calibration.

Specifications:
  • Measurement Range and Resolution: See Table below; automatically selected- on an individual channel basis- when the channel is configured*
  • Excitation (per channel): As required for thermolinear transducer
  • Amplifier (per channel):
      Input Impedance: As required for thermolinear transducer
      Offset: Initial: ±0.02% of full scale; vs. Temperature: ±50 ppm/°C; vs. Time: ±20 ppm/month
      Gain Accuracy: ±0.02% of full scale (absolute maximum input voltage range without damage is ±9 V
      Gain Stability: vs. Temperature: ±50 ppm/°C; vs. Time: ±20 ppm/month
  • Filter (per channel): 1-pole modified Butterworth; 3 dB down at 30 Hz; 60 dB down at 100 kHz
      Step-Response Settling Time (Full-Scale Output):
      To 1% of final value: 30 msec
      To 0.1% of final value: 60 msec
      To 0.02% of final value: 250 msec
  • Total System Accuracy (typical, including Model 10A15-8, probe interchangeability, and system data collection and processing): see Table below
  • Auxiliary Outputs: None
    *In System 10, all 10A15-8 channels are given a “type” code of “55” and employ a special range/resolution selection procedure.
