The Ashcroft ATE-2 calibrator is
designed to measure pressure, tempera­ture, voltage or current. It includes the
capability to display up to two modules
and one electrical measurement simulta­neously, along with logging data to inter­nal memory or communicating directly to
a PC via USB connection.
The ATE-2 has a wide selection of pres­sure modules, covering ranges from 0.25
inches H20 through 10,000 psi. The base
unit design allows the user to operate
one or two modules. Modules are inter­changeable, and can be changed without
the need of tools, minimizing downtime.

The ATE-2 provides a large LCD
display for ease of reading measurements
and configuring the calibrator.
The unique product platform also
includes data logging; with internal
storage capacity for up to 16,000 records
on up to 64 data log files that can be
transferred to an SD card.
A wide range of approvals including UL,
FM, ATEX and CSA make the ATE-2
a popular choice worldwide.

ATE-2 Hand Held Calibrator

ATE-2 STANDARD FUNCTIONS

• Data logging allows the user to save
pressure, temperature and or electronic
values displayed on the LCD to internal
memory. Internal memory can hold up
to 64 data log files and a total of up
to 16,000 individual records. Manual
logging is initiated with a single key
press. Automatic data logging can be
programmed to collect data at timed
intervals between 0.1 second and 24
hours.

• SD Memory Card Slot gives the ATE-2
additional data storage capability limited
only by the capacity of the SD card
installed. Data logs stored on the SD
card are saved in .csv format which
can be read by most spreadsheet
programs. Data can easily be trans­ferred from the ATE-2 to a PC.

• Loop Power Supply is a standard
feature on non-I.S. units, and allows the
user to conveniently power the device
under test with 24Vdc up to 35mA.

• Percent Error Function can be used
when calibrating pressure transducers.
Calculations are performed by the
ATE-2 eliminating potential for human
errors. This function enables the user
to program the full scale range and
electrical output of the transducer
under test and will display the actual
pressure and electrical output readings
as well as a percentage value compar­ing the actual output to the theoretical
output.

• Switch Test Function allows the oper-
ator to calibrate and document the
pressure switch function. The on-board
display will show pressure switch trip
point, reset point and will calculate
switch deadband. All calculations are
performed by the ATE-2 eliminating
potential for human errors.

• Dual Mode Function allows the oper-
ator to add or subtract the measured
pressure values from two installed
Quick-Select™ pressure modules. This
allows for measurement of “high-line”
or elevated static differential pressures.
This feature also offers the ability to
add barometric pressure from an abso­lute pressure module to the measured
pressure from a gauge pressure mod­ule, giving the user the ability to mea­sure a variety of absolute pressures
without using designated modules.

be quickly interchanged (“hot-swapped”)
without the use of tools, and are auto­matically recognized once installed in the

Ashcroft Low Pressure Module AM2-1

The AM2-1 Quick-Select low pressure
module is based on a proprietary, vari­able-capacitance sensor. This sensor is
available in ranges from 0.25 to 0/200
inches H20 with accuracies from ±0.1%
to ±0.06% of span, and are available for
gauge, differential and compound pres­sures. They are suitable for use with dry,
non-corrosive gases
The variable-capacitance sensing
element incorporates a micro-machined
silicon diaphragm. Silicon provides opti­mum repeatability with minimal hysteresis.
The sensor is extremely stable, due to the
sputtered metal capacitance plates being
molecularly bonded to the silicon. This
design eliminates adhesives from the sen­sor assembly.
The AM2-1 sensor is also extremely
rugged. It can withstand extreme over­pressure, shock and vibration without sig­nificant error or calibration offset.

Ashcroft Medium / High Pressure
Module AM2-2

The AM2-2 Quick-Select pressure
module incorporates a piezoresistive,
micro-machined silicon sensor. These
sensors are available in ranges from 5 psi
through 0-10,000 psi, and are also offered
in absolute, vacuum and compound
ranges with accuracies from 0.025% to

0.1% of span. 316 SS sensor isolation is
provided on all ranges except for 10,000
psi which is 17-4 PH stainless steel, and
is suitable for applications involving fluids
or corrosive gases.
Optional enhanced accuracy eliminates
temperature error over the entire compen­sated temperature range of high pressure
modules.

The Ashcroft ATE-2 provides accurate tempera­ture measurement when using the AM2-RT module
with an RTD probe. This system supports the most
common RTD’s without requiring operator input of
probe characterization data; each module comes
factory-programmed with standard curves for

probes.

The setup menu allows the operator to choose
configurations for 2, 3 or 4 wire RTD probes and
decimal resolution. The temperature measurement
system includes the ability to automatically track
minimum / maximum values.

MODULE FEATURES

• Allows ATE-2 to measure tempera-

ture with a thermocouple

• Pre-programmed to accept 8 most

common thermocouple types

• Selectable units of measure: Celsius,

Fahrenheit, Kelvin, Rankine and
millivolts

• Reference junctions: automatic

internal or manual external

With the AM2-TC1 interface module installed, the
ATE-2 contains programming to read types J, K,
T, E, R, S, B and N thermocouples and display the
measurement in units of temperature measure or
millivolts. Other types of thermocouples may also be
read by using the direct millivolt readout.

Reference Junction (selectable):
Automatic Mode: The AM2-TC1 module incorpo-

rates an internal resistor/thermistor based reference
junction, which may be selected for use in the tem­perature readout mode.

Manual Mode: An external reference junction may
be used in place of the internal junction. External ref­erence junctions may be applied in the temperature
or direct millivolt readout modes.

Resolution Reading in Temperature Units
(selectable):

1, .1 or .01 degrees. “Auto” mode selection that
allows the ATE-2 to automatically configure the read­out to the highest significant resolution
(resolution closest to the tolerance) for the thermo­couple type selected.

Resolution Reading in Millivolts:

Thermocouple Connection
(to interface module):

Requires a “miniature thermocouple connector”
(Omega type SMP), specifically matched to the ther­mocouple type to be used. These connectors may be
purchased as an accessory under the following part

AMBIENT TEMPERATURE EFFECT:

To calculate, multiply degrees deviation from
25°C times the value listed in the far right column
of the listed table. Only applied when using the
internal reference junction, within the ambient
window of 0-50°C.

TO CALCULATE TOTAL SYSTEM/MEASUREMENT
ACCURACY:

Accuracy = System Accuracy @ 25°C + System
Ambient Temperature Effect + Inaccuracy of
Thermocouple Device

SYSTEM ACCURACY (BASED ON DIRECT
MILLIVOLT READING FROM THERMOCOUPLE):

Includes the base unit and AM2-TC1 interface
module. (Does not include inaccuracy due to the
thermocouple device. Reference junction not
applicable to direct millivolt readings.)
