11.11 Measurements in Electronics. BAT-10 and ICT-4 provide the quickest and cheapest method of getting accurate reading on both discreet components and integrated circuits used in electronic equipment. ICT-4 has two important differences from the regular MT-4 probe. There is a 5 1/2” handle suitable for use in the hand or in a micromanipulator and the micro-thermocouple protrudes slightly beyond the steel sheath and has some thermal isolation from it.
rial. In liquids and semi-solids, the tip and sheath are simply immersed; on solid surfaces, the sheath is laid against the surface. Here is a useful rough rule: Heat leakage effects are substantially reduced when an amount of probe equal to 10 or more sheath diameters is immersed or laid on the surface. For example, with a probe of 1/16” diameter: 10 x 1/16” = 10/16” = .625” = the minimum immersion depth 11.7 Errors between thermocouple probes.
11.0 TEMPERATURE MEASUREMENT WITH THERMOCOUPLE SENSORS 11.1 The thermocouple is a simple and widely accepted device for measuring temperature. It comprises two wires of dissimilar metals fused together to form a junction which produces an electrical output proportional to temperature.
10.0 SPECIFICATIONS Temperature Range and Resolution: -200°C to +400°C, 1°C resolution -100°C to +199.9°C, 0.1°C resolution Differential Temperature Range: -19.99°C to +19.99°C. Linearization centered at 40°C See Section 5.0 Accuracy: 1°C, (±1 digit) 0.1°C, (±1 digit) 0.01°C (±1 digit) 1° Range 0.1° Range Diff.
.0 ANALOG OUTPUT FOR CHART RECORDING 7.1 NON-LINEARIZED ANALOG OUTPUT. BAT-10 is supplied with an analog output that is proportional to the input thermocouple voltage with respect to analog common. This is adequate for most stirp chart recording applications where small temperature ranges are involved. The output bears a non-linear relationship to temperature and thermocouple tables can be used to compensate for linearity changes over wider temperature ranges.
When using BAT-10 for differential measurements not centered on the 40°C reference, a correction must be introduced to accomodate changes in sensitivity and linearization at different reference temperatures. In general, differential measurements are quite correct when the difference reading is small and both sensors are in the 20-60°C range.
4.2 Select the required range by depressing the 1° or 0.1° RANGE SELECT pushbutton. Be sure that the DIFF pushbutton is not depressed. 4.3 Direct measurements are made with inputs 1 and 2. If two probes are being used, just depress the PROBE SELECT pushbutton which corresponds with the sensor to be monitored. 5.0 5.1 5.2 5.3 DIFFERENTIAL MEASUREMENT TECHNIQUES Specifications of the differential range are as follows: Resolution 0.01°C Accuracy 0.01°C (±1 digit) Repeatability 0.
1.0 INTRODUCTION 1.0 Physitemp laboratory thermometers are compact, digital thermometers for use with type T thermocouple sensors. The BAT-10 thermometer has two probe inputs for direct temperature readings with a resolution of 0.1°C or 1°C. A third input is used when differential measurements are made. On the differential range, temperature resolution is 0.01°C. BAT-10 accepts all Physitemp type T thermocouple probes. 2.0 INITIAL INSTALLATION 2.
