Proline Promass Q 500 PROFIBUS PA Electrical connection
Hauser 37
Operating temperature When mounted in a fixed position: –50 to +105 °C (–58 to +221 °F); when cable
can move freely: –25 to +105 °C (–13 to +221 °F)
Available cable length Fixed: 20 m (65 ft); variable: up to maximum 50 m (165 ft)
Connecting cable for sensor - Proline 500 transmitter
Standard cable
6 × 0.38 mm 2 PVC cable with common shield and individual shielded cores
Conductor resistance ≤50 Ω/km (0.015 Ω/ft)
Capacitance: core/shield ≤420 pF/m (128 pF/ft)
Cable length (max.) 20 m (65 ft)
Cable lengths (available
for order) 5 m (15 ft), 10 m (32 ft), 20 m (65 ft)
Operating temperature max. 105 °C (221 °F)
Operation in zones of severe electrical interference
The measuring system meets the general safety requirements →  269 and EMC
specifications →  258.
Grounding is by means of the ground terminal provided for the purpose inside the
connection housing. The stripped and twisted lengths of cable shield to the ground
terminal must be as short as possible.
7.1.3 Terminal assignment
Transmitter: supply voltage, input/outputs
The terminal assignment of the inputs and outputs depends on the individual order
version of the device. The device-specific terminal assignment is documented on an
adhesive label in the terminal cover.

Transmitter and sensor connection housing: connecting cable
The sensor and transmitter, which are mounted in separate locations, are interconnected
by a connecting cable. The cable is connected via the sensor connection housing and the
transmitter housing.
