Another addition to the range of thermocouple temperature indicators manufactured by STP Ltd of Sittingbourne. Kent. UK. is the Multltemp Model 6711CA, illustrated below Model 6711CA provides an easy method of measuring the temperatures of mckel chromium/nickel alumlnlum thermocouples in the range +40 to -190 C Up to twelve of these thermocouples can be connected to the Indicator at any one time, and their respective measurements obtained by using the twelve-position isolating switch The temperature scale has a 10: span and is supplemented by a range switch which selects the scale in 10 c steps The model is fully portable, and contains a small, battery-controlled solid state amplifier and an output socket by which it can be connected to a standard resistor
Thermo Electric International Ltd, Maldstone, Kent, UK, have added Kapton (a DuPont trade mark) polymlde to its selection of thermocouple wire insulations Particular benefits in aerospace applications are a saving of 25 ~o ~ in weight and 50 ~o in space, and a temperature range from -450 to +750 F
The new Insulation gives thermocouple and extension wires high d~electrlc strength and high dielectric constant, high radiation and abrasion resistance, high chemical resistance to moisture and fungus, and a self extinguishlng ability after being subjected to flame
