7230 HT Multivariable Digital Probe Data Sheet

Proven Magnetostrictive Sensing Performance
Integrated with a Modbus or ASCII Digital
Multivariable Protocol

The 7230 HT Digital Probe is a new
magnetostrictive level measurement probe
from Ametek APT for the up-stream oil
and gas industry where multi-layer and
temperature data is critical to everyday
operations.

The 7230 Probe is a level measurement
solution that provides both total and
interface levels as well as temperature
readings from up to 5 discreet positions,
and can measure up to 257 F. All the data

o

is collected by installing a single sensor
through a single process connection,
eliminating the need for multiple sensors
and insertion points. The 7230 Series is
approved as Explosion Proof (without
intrinsic safety barriers) for Class I, Div. 1
and Zone 1 hazardous locations.

The 7230 is available with a choice
of either Modbus RTU or ASCII
communication protocols. An optional
analog interface module is also available
for use with the Modbus RTU output. This
option allows for multivariable 4-20mA
outputs.

All of this performance is enhanced by
Ametek APT’s patented magnetostrictive
design. Magnetostrictive technology
requires no calibration yet provides the
highest accuracy of any of the most
popular level technologies that are
currently offered in today’s market. The
7230 Probe is no exception, as it exceeds
the high accuracy of the proven 7330
Analog STIK with an impressive accuracy
of 0.01% of measured span.
