Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 

The TBTD-* series and TSR* series resistance temperature devices (RTDs) are typically used to measure the internal temperature of motors/generators. The TBTD-* series RTDs are bearing temperature detectors, whereas the TSR* series RTDs are slot resistance thermometers.

Both series are available with 2, 3 or 4-wire options and are connected by means of flying leads to an intrinsically safe supply and have the following entity parameters:
Ui = 12 VIi = 35 mAPi = 105 mW
Ci = cable capacitance only
Li = cable inductance only
The type numbers are as follows:
·          TBTD-*-series bearing temperature detectors (where * = K, L or O)
·          TSR*-series stator winding temperature detectors (where * = B, C, D or K)

 

Schedule of Limitations

1.

The RTDs have been assessed for an ambient range of -50°C to +180°C. The maximum temperature rise does not exceed 13ºK above ambient.

2.

The RTDs may be used in flammable dust zones (20, 21 and 22) provided they are inside a suitably-certified enclosure.

3.

TSR-* series only: where the insulated wiring has no overall sheath, the conductor insulation has a minimum thickness of only 0.09 mm (code Z) or 0.12 mm (codes Q, R, W, X, Y), so precautions shall be taken to prevent contact with other current-carrying conductors, for example by the use of additional insulation or routing away from other conductors.
