This document is a component maintenance manual for the Scientific Instruments B7000 Air Temperature Sensor. It describes the unit's configuration, which consists of a calibrated thermistor and trimming resistor housed in a stainless steel probe with an MS connector.
The manual provides specifications such as operating temperature ranges from -55°F to +550°F and nominal resistance values at specific temperatures. It details procedures for testing, fault isolation, disassembly (not applicable), cleaning, visual checks, and repair. Notably, the sensor is considered non-repairable except for carefully straightening bent receptacle pins; other defects require discarding the unit.
| Operating Ambient Temperature Range | -55°F to +550°F (-48.3°C to +287.8°C) |
|---|---|
| Nominal Sensor Resistance at 77°F | 104 K ohms |
| Nominal Sensor Resistance at 445°F | 352 ohms |
| Receptacle Type | MS3102E10SL4P |
| Mating Plug Type | MS3106A10SL4S |
| Weight | 4 oz (0.1 kg) |
| Probe Diameter Maximum | 0.215 in. (5.46 mm) |
| Overall Length Maximum | 3.81 in. (96.84 mm) |
The temperature sensor is considered non-repairable, though bent receptacle pins may be carefully straightened.
The temperature sensor should be discarded.
