RTD
APEX make Resistance Temperature Detector (RTD)
sensors consist of a high purity electrical resistance wire ,
non inductively wound on a ceramic or glass base material . The
resistance of this sensor is temperature dependent .
Types of RTD :
-
Pt-100 /
Pt-500 / Pt-1000 / Pt- 53
-
Standard Element
in Simplex or Duplex type ( 2 wire or 3 wire )
-
Range : (-)
200 deg C to + 600 deg C
Thermocouple
APEX make thermocouple is a simple device that
is formed by joining two dissimilar metals at one end ( Hot Junction
) . A small emf ( voltage ) is generated between the other open
end ( Cold Junction ) that is strictly dependent on the difference
in temperature between the Hot and Cold Junction .
- Types : J /
K / R / S / T / E / B
- Ranges : From
(–) 200 Deg C to 1800 Deg C depending on the thermocouple
.
- Standard construction
in Simplex or Duplex type .
Mineral Insulated Element
( MI )
are insulated with tightly compacted magnesium oxide powder enclosed
in various sheath . The sheath can be bent or twisted to suit various
application and can have length upto several meters .
- Types : RTD
or Thermocouple / Simplex or Duplex Type
Compensating Cables
These are used to connect the temperature sensors
to the temperature indicator . Available in PVC / SS Braiding /
Fibre Glass / Teflon coated / Asbestos sheathing .
Plugs
These are used to join the temperature sensors to
temperature indiators . |
