Note
SITRANS TS500 barstock version (only European portfolio 7MC752..)
For SITRANS TS500 barstock version without flange (type 4), the customer has to complete the mounting of the device
extension to the protective tube, see Device extension and protective tube torque requirements table below
CAUTION
Gasket between extension and protective tube
Gasket between device extension and protective tube can only be used once
● Use required torque values between device extension and protective tube, see Device extension and protective tube
torque requirements table below.
● Use required torque values between the device head and extension if customer adjustments are necessary (M24
connections only), see Device head and extension torque requirements table below.

Rule of thumb for installation
Prevent faults caused by heat dissipation by observing the following rules:
● Select the largest possible immersion depth. Estimate the immersion depth using the formulas specified below.
● Select a measuring location with a high flow rate.
● Ensure that there is sufficient thermal insulation of the external components of the thermometer.
● Ensure that external parts have as small surfaces as possible.
● Select the optimum mounting position for the process in question.
Estimation of immersion depth
Medium Immersion depth (calculation)
Water Immersion depth ≥ TSL + (5 x ∅
Air Immersion depth ≥ TSL + (10 to 15 x ∅
TSL = Temperature Sensitive Length
