1 Overview
The high-precision TORRIX level sensor is designed to provide continuous gauging of liquid
media levels in tanks. The measuring principle used by the sensor exploits the physical effect
of magnetostriction and is largely unaffected by temperature. This method is particularly
ideal where level measurements are required to be extremely accurate, such as in the chem-
ical industry.
In this documentation, the TORRIX is described with cable connection on the side of the
probe head. This connection can be an M12 cable gland (also with M16 adapter), an M12
plug, or an M20 resp. ½in NPT internal thread.
A further variant is the TORRIX M12 with an M12 plug connector on top of the sensor cap,

Technical documentation TORRIX M12, art. no. 350164
The TORRIX supplies a 4 ... 20 mA output signal which is configured using buttons in the
probe head, or a digital output signal as HART ® protocol. Probe lengths are possible from
100 mm to 6 m, as Flex version up to 10 m, as well as versions for different temperature
and pressure ranges.
It also comes in the following versions:
• TORRIX (with screw-in unit, welded or for stepless positioning)
• TORRIX flange (with process connection flange)
• TORRIX Flex (with flexible probe tube)
• TORRIX Bypass (for installation on a bypass with magnetic float)
• TORRIX 90 (with 90° angled probe head)
• TORRIX 6 (with 6 mm probe tube)
• TORRIX 6B (with 6 mm probe tube and short cable gland)

The TORRIX versions can also be supplied as Ex version:
The level sensor TORRIX Ex … with Ex approval (ATEX, IECEx) can be installed in potentially
explosive areas which require equipment protection level Ga (Ex Zone 0), Ga/Gb (Ex Zone
0/1) or Gb (Ex Zone 1) for electrical equipment.
