Calculate the capacitance for a time constant of 65

μ

Sec, using the following formula:

(time constant = Resistance * Capacitance)

is the sum of the load resistor and cable resistance.

is the sum of the cable capacitance and the capacitances of the connected

device/devices.

The time constant of the complete setup is given by:

Where

= The resistance of the HART sensing resistor

= The resistance per meter of cable

= the length of the cable

= the capacitance of the LC500 = 68 nF

= the capacitance per meter of cable

Example

A twisted pair cable with a conductor cross-section of 1 mm

2

(AWG 18 equivalent) has

a copper resistance of 73.6 Ohm/km and a capacitance of 100 pF/m (or 1 nF/10m).

For a standard 250 Ohm sensing resistance, with a 100 meter cable:

= 250 Ohm

= 0.0736 Ohm/meter

= 100 m

= 68 nF

= 0.1 nF/m

Since 20



s

is less than 65



s

, 100 meters of this cable is suitable.

Multi-drop applications: maximum cable length

In a multi-drop application, the total capacitance of all the devices must be calculated.
With three devices, at 3 x 68 nF, the allowable cable length will be considerably limited.

Terminals

Pointek CLS500 is equipped with two terminal blocks, both insensitive to polarity.

•

One terminal block

connects the instrument cable (loop power).

Notes:

•

If the device is part of a multi-drop setup, Pointek CLS500 sets the current to 4 mA,
which inhibits analog signalling, including fault signalling.

•

Multi-drop is a HART mode where devices are set to a fixed current, and the
device is interrogated periodically. The maximum number of devices on one loop
is 15, one of which can be an analog mode device.
