Thank you for choosing a NIVELCO instrument.
We are sure that you will be satisfied throughout its use!
1. APPLICATION
THERMOCONT TXP resistance thermometers with drilled thermo-well case are used as sensors of temperature measurement in industrial
process control, especially in the gas industry. The temperature sensors are suitable for temperature measurement of various kinds
of gaseous media inside pipelines, tanks or furnaces. The heat-sink on the outer protection tube provides accurate measurement
independently from the ambient temperature. The mechanical and vibration-protection requirements are met by double pipe construction
including the inner and outer tube and well. Process connection and electrical connection are provided as detailed below. Sealing of the wiring
cables are provided by the cable glands.
The outer protection tube is a drilled thermo-well case made from stainless steel. The cover of housing has a security chain against loss.
The Pt100 temperature sensor can be replaced without removing the instrument from the process.

3. MOUNTING
The temperature sensor instruments have threaded process
connection. Sealing of the wiring cables are provided by the
cable glands. The cable glands can be normal or Ex approved
type.
4. SPECIAL CONDITIONS FOR SAFE USEAGE
Do not remove the housing cover when energized!
The housing of the device must be connected to the
equipotential network.
The device must be operated only with using properly sealed
Ex d IIC or Ex d IIB certified protective cable gland.
The unused cable gland connection should be closed with
certified closing bolt.
When the wiring is finished and the housing cover is closed
the security chain should be mounted.
Take into consideration that process connection of the
instrument could be the same as the temperature of the
medium to be measured. So the temperature class of the
applied instrument depends on the highest medium
temperature.
Tightening torque for the NPT 1” process connection types
should be 45 Nm.
The II 1/2 G Ex d ia IIB T__ Gb approved temperature sensor
devices must be operated from certified [Ex ia] IIC
or [Ex ia] IIB approved intrinsically safe circuits complying with
the following technical specifications:
Uomax <= 30V, Iomax <= 100mA, Pomax <= 750mW.
6. MAINTENANCE, REPAIR
The devices do not require maintenance on a regular basis. In some
instances, the sensor probe may need occasional cleaning to remove
surface deposits. This must be carried out gently, without harming the
sensor. Repairs during or after the warranty period are effected at the
Manufacturers.
7. STORAGE CONDITIONS
Ambient temperature: -25 °C ... +55 °C.
