P/N 20549SI LOOP CONTROLLER

Introduce：

This tool has as function to measure principal features of aircraft fire detection loop such as the Airbus, Bombardier, ATR 42 & 72's, Boeing, MacDonnel Douglas and BAE aircrafts:

Parallel resistance
Parallel capacitance

It is used during the checking operations of the loops and their wiring aircraft in assembly line (except Thermocoax ©) . It is also used during maintenance on track.

The supported loops are Fenwall© CFD P/N 35xxx-y-255

It provides 3 distinct modes of measurement:

• "CONTINUITY“ mode to measure the core continuity(sensitive element).

• "INSULATION“ mode to measure Fenwall© loop insulation (Zc)

The Advantages：

1 - The only Loop Controller in accordance with all the technical specifications of the sensor Loop manufacturer FENWALL.

2 - Small, light weight and completely autonomous lending convenience to the assembly line, line and heavy maintenance.

Data Sheet：

FunctionFunctions:

• "CONT" 1 to 99 Ohms mode to measure the core continuity (sensitive element) with precision of 1%.

• “INSUL" mode to measure Fenwall© loop insulation resistance. In this mode, the tool measures the loop parallel capacitance and computes its equivalent impedance at 1 KHz. Zc = 1KOhms (C~156nF) to 5 MOhms (C~31pF) with a full scale precision of 5%. The displayed value is the impedance of parallel capacitance (Zc in Ohms).

•Input measurement:

3 x 4mm banana plugs inputs ( 2 for Continuity measurement connection and 1 for Insulation measurement connection to be combined with 2 others plugs )

•Displays:

Large LCD displays easy to read with backlight
