PCL-1B, $1845, with 2 plug-in modules, PCL-MB-030G, $1110, and PCL-MB-3KG, $1265.

The OMEGA®PCL-1B pressure calibrators are full featured handheld instruments that can measure pressure, temperature, flow, vacuum, leak, current, voltage, and change of state for switch testing—virtually all pressure measurement and test functions that an application would require.

A complete PCL-1B system consists of a base unit and 1 or 2 plug-in modules. Pressure modules are available in full scale ranges between 0.25 inH2O and 7500 psi and in gage, vacuum, absolute, differential, and compound pressure types. Three temperature modules are available,

for thermocouple (J, K, T, E, R, S, B, and N calibrations), and RTDs (Pt100, Ni120 and Cu120 or Pt1000 types).

When installed in the base unit, these quick-select modules not only afford unparalleled measurement flexibility; they also help protect the pressure sensor from damage. Modules can be switched in just seconds, without tools. In addition to its keypad features (see diagram on next page), the base unit can link to a computer, data acquisition system, or dumb terminal via a standard RS232 connection.

The PCL-1B can accept two removable PCL-M pressure modules, modules sold separately, see page A-42.

HANDHELD CALIBRATORS WITH INTERCHANGEABLE PRESSURE MODULES

Interchangable PCL-M plug-in modules.

Allows selection of pressure or electrical

measurements on each port.

Allows entry into menu-driven system

configuration to establish timer functions,

percent readout for transmitter calibration,

level of damping, parameters for leak and

flow testing and various other modes

of operation.

2-line LCD with 16 characters per line. Displays the measured pressure from 1 or 2 quick-select modules simultaneously or displays the measurement from either of two sensors and the corresponding value of a current or voltage input.

Turns system on or off. Auto-off

feature can be activated through

Checks and displays remaining

Displays the measured pressure in any of

13 selectable engineering units. Includes 1

user-programmable engineering unit.

Tests for leaks in either cc/min

or pressure decay over time.

When used with a pitot tube or anubar,

converts differential pressure

measurement to a flow velocity or a flow

volume measurement for air-flow

Monitors and displays on demand the maximum and minimum pressure values measured.

Tares the display to eliminate a pressure preload. Display flashes when unit is in tare mode.

Optional feature that stores measured values in on-board memory. Measured values can be logged manually, automatically or automatically with delayed starting time.

Tests pressure switch, providing trip point, reset point and deadband value.
