Many areas of process plant demand temperature sensors with a
rugged construction to meet both the demands of the process and
the installation environment. A thermowell machined from solid bar
stock offers a higher integrity for those more demanding process parameters
and a flanged process connection enables it’s use in higher
process pressures. The choice of connection head type and extension
also allows a specification to be drawn up that will satisfy most requirements.

Spring loaded insert
Sheath :	321, 316L or 310 stainless steel, 6mm OD (length to suit thermowell) and fitted with a spring loaded ceramic terminal block.
Resistance Thermometer
Detector :	single or duplex PT100 with 3 wire connection , Class ‘B’ or ‘A’ tolerance and to BS EN 60751:1996.
Operating range :	-50 to +380°C (-58 to+716°F)
Thermocouple
Element :	single, duplex or triplex elements, types ‘T’ (Cu/ Con), ‘E’ (NiCr/Con), ‘J’ (Fe/Con) ‘K’ (NiCr/NiAl) or ‘N’ (Nicrosil/Nisil) to BS EN 60584-1:1996.
Operating range :	-50 to +850°C (-58 to+1562°F), depending on thermocouple type.

A temperature transmitter with a 4 to 20mA output can be supplied in place
of the connection block for both hazardous and non-hazardous duties. Other
dimensions and tolerances outside the above specifications may also be
available on application.
