Function and system design

Measuring principle Electronic recording and conversion of input signals in industrial temperature measurement. A

platinum sensor located at the measuring tip changes its resistance value depending on the
temperature. This resistance value is recorded electronically. The relation of the measured resistance
value and temperature is defined by the international standard IEC 60751.

Power supply failure • Behaviour in case of overvoltage (> 30 V)

The device works continuously up to 34 V DC without any damage.
No damage is caused to the device in case of a short-term overvoltage up to 1 kV (as per
EN 61000-4-5). The specific properties are no longer guaranteed if the supply voltage is exceeded

• Behaviour in case of undervoltage
If the supply voltage drops below the minimum value, the device switches off (status as if not
supplied with power = switch open).

Maximum permitted process pressure

L = insertion length
p = process pressure

The diagram takes into consideration not only the overpressure but also the pressure load caused by
the flow, whereby a safety factor of 1.9 has been specified for operation with flow. The maximum
permitted static operating pressure is lower at greater insertion lengths due to the increased bending
load caused by the flow. The calculation assumes the maximum permitted medium velocity for the
respective insertion length (see diagram below).

The maximum process pressure for the conical metal-metal hygienic process connection (Option MB)
is 16 bar (232 PSI)!

The permitted flow velocity is the minimum from resonance velocity (resonance distance 80%) and
load or buckling caused by flow, which would lead to failure of the thermometer tube or to exceedance
of the safety factor (1.9). Calculation was performed for the specified limit operating conditions of
200 °C (392 °F) and  100 bar (1450 PSI) process pressure.

Switch point functions

• Hysteresis function
The hysteresis function enables two-point control via a hysteresis. Depending on the temperature T,
the hysteresis can be set via the switch point SP and the switch-back point RSP.

• Window function
The window function enables the setting of a process window.

• NO contact or NC contact
This switch function is freely selectable.

• Delay times for switch point SP and switch-back point can be set in increments of 1 s. By this means
undesirable temperature peaks of short duration or of high frequency can be filtered out.
