3.2 Cables
The 4500HT Series are delivered with either mineral insulated cables (4 solid, 22 gage
copper conductors in magnesium oxide inside a 316 stainless steel tube), or with Teflon
®
insulated cables inside stainless steel tubing with couplings or Teflon insulated
conductors in a continuous stainless steel tube. The Tubing is delivered in coils and can
be terminated with a connector, a transition to a regular instrumentation cable, or other
as determined by the customer.

Cable lengths of several kilometers are possible and the frequency output signal is not
affected by changing cable resistances (caused by splicing, changes of length, terminal
contact resistances, etc.), nor by penetration of moisture into the electronic circuitry.
These sensors are designed for static measurements only and at least one second is
required to excite and read the sensor.
