TDA-100P Automatic Filter Tester
Locally Operated Configuration
Fully Integrated Configuration
Description
The new TDA-100P Automatic Filter Tester utilizes state-of-the-art
technology and microprocessor control. This new design features
a user-friendly interface to minimize setup and operator training.
All functions and operating parameters of the TDA-100P can
be programmed using just 4 function keys and the menus are
shown on an easy-to read, alphanumeric, vacuum fluorescent
(VF) display.
Features
The test parameters for Percent Penetration, Filter Resistance,
and Filter Test Flow are shown on individual digital display
panels. All three test parameters have individually adjustable
alarm set points which are continuously monitored by the microprocessor.
Should a parameter exceed its set point, the FAIL light will
illuminate and the parameter's digital display will flash.
Testing will not be permitted until the alarm is reset.
The microprocessor self-checks the system during operation
and the FAULT light alerts the operator to any system faults.
The specific problem causing the fault is identified on the
VF display. The near mono-dispersed aerosol is also microprocessor
controlled, allowing fully automatic, unattended operation
when integrated into an automated production line.
The new TDA-100P Automatic Filter Tester is housed in a compact,
tabletop cabinet which features an ergonomic front control
panel. The TDA-100P has new safety features on its test fixture
that can be configured to accommodate any canister filter
manufactured today or in the future. An RS-232 port and user
interface on the TDA-100P give the capability of data collection
for SPC purposes and control of the machine by remote PC.
