BULLETIN ATE-100

The Ashcroft® ATE-100 handheld system
introduces a new era in pressure calibration
standards. This unique instrument measures pressure, temperature, flow, vacuum,
leak, current, voltage and change-of-state
for switch testing. A fully equipped ATE100 system provides all calibration capabilities needed in virtually all pressure
measurement and test applications.
Each handheld system consists of a
base unit and one or two Quick-Select™
pressure modules. An array of pressure
modules is available to cover ranges from
0.25 inches H2O through 10,000 psi.
Modules can be inter-changed quickly and
easily without the use of tools. In addition
to pressure measurement, Quick-Select
interface modules are also available to
allow the ATE-100 to measure temperature with common RTDs or thermocouple
devices.
For the most demanding applications,
the ATE-100 can be optionally con-figured
in an intrinsically safe “FM approved” version, for use in Class 1, Div. 1 hazardous
environments. In areas where EMI/RFI
immunity is required, an optional “CE
Mark” version is also available.
With a broad variety of ranges and features, the ATE-100 is one of the most powerful, versatile and useful test and measurement instruments available today.

All specifications are subject to change without notice.
All sales subject to standard terms and conditions.

The Quick-Select Pressure Module
Quick-Select pressure modules are
available in full-scale ranges from
0.25 inches H2O through 10,000 psi.
Gauge, vacuum, absolute, differential or
compound pressure ranges are available.
Each base unit can accommodate two
pressure sensor modules simultaneously.
Select from multiple modules which can be
interchanged in seconds without the use of
tools. When installed in the base unit, a
pressure module becomes an integral part
of the measurement system, thereby protecting the sensor from damage. Any combination of Quick-Select pressure modules
may be used or interchanged as needed
in the lab or field.
The AQS-1 Module
The AQS-1 Quick-Select low pressure
module is based on a proprietary, Ashcroft
engineered, variable-capacitance sensor.
This sensor is available in ranges from
0/0.25 to 0/200 inches H2O. AQS-1 QuickSelect pressure modules are available in
accuracies from ±0.1% to ±0.06% of span.
These Quick-Select pressure modules are
available for gauge, differential and compound measurement requirements.
The variable-capacitance sensing element in the AQS-1 incorporates a micromachined silicon diaphragm. Silicon provides optimum repeatability with minimal
hysteresis. The sensor is extremely stable,
since the sputtered metal capacitance
plates are molecularly bonded to the silicon. This design allows for the elimination
of epoxies and other types of bonding and
adhesive agents from the sensor assembly.
The AQS-1 sensor is also extremely
rugged. It can withstand extreme overpressure without significant error or calibration
offset. In addition, the sensor is capable of
withstanding significant shock and vibration without damage or loss of measurement output integrity.
The AQS-2 Module
The AQS-2 Quick-Select pressure module incorporates a piezoresistive, micromachined silicon sensor. These sensors
are available in ranges from 0/100 inches
H2O through 0/10,000 psi and are also
offered in gauge, absolute, vacuum and
compound variants.
