TF-100™ Series
Vibrating Tuning Fork

Application
The TF‑100 Series Point Level Switch
is designed for reliable indication of
liquids and light slurries. The output
can be set to indicate alarm on either
high level for spill prevention, or low
level for run-dry protection.

Versatility
This versatile level switch requires no
calibration and is available with relay,
transistor, or current outputs.

Easy Installation

The TF-100 requires no calibration.
Install, connect power and outputs, and
you're done.

Compact Design

Integral electronics with sensor lengths as
short as 1.9" (47mm) makes this switch
ideal for limited space installations.

The electronic module responds
to changes in frequency from an
uncovered to a covered fork. As
such, it is immune to changes in
electrical properties of the material.
This allows the TF‑100 Series to be
used in vessels that can have either
conductive or insulating liquids.

Reliability

Internal Self-Check feature monitors the
electronics and sensor. If there is a fault,
the output switches to the Alarm State.

Output
• TF‑L includes a DPDT relay output for
local control of pumps, valves, or alarm
indication.
• TF‑P offers PNP or NPN transistor
output.
• TF‑T is a current output switch
(8 mA / 16 mA).

Maintenance Free
When used in accordance with
installation guidelines the TF‑100
Series - Vibrating Tuning Fork requires
no routine maintenance.

Sanitary
Sanitary models are available for
Pharmaceutical and Food & Beverage
applications.
