Sauter Components TFL 611 Series Quick Start Manual

TFL 611: Continuous frost monitor with capillary sensor
How energy efficiency is improved
Demand-led, large-scale monitoring of installation parts with fully active sensor.
Areas of application
Temperature monitoring in air/water heat exchangers and air ducting with constant frost-protection
control, frost-protection switch and temperature transmission. For applications on the air side of instal-
lations.

1)
The accessory 0292146 001 for duct fitting must be ordered separately.
2)
If under inductive load, take RC circuit into account.
3)
The monitor always reacts to the coldest place (minimum length is 250 mm).
4)
The head of the instrument is frost protected for ambient temperatures up to max. -15 °C by a heating system.
Operation
Using a vapour-filled capillary tube and diaphragm system, the frost monitor measures the lowest
temperature that occurs anywhere along at least 250 mm of the capillary tube.
If the monitor is correctly positioned at the air outlet of the heating coil, it measures the lowest temper-
ature even if there are strata of differing air temperatures. In so doing, the steam pressure causes a
movement of the diaphragm capsule in the capillary tube. By means of an inductive measuring sys-
tem, this movement is converted into an electric signal and is amplified electronically; it then creates a
0...10 V d.c. measuring signal.
