The KMPS series pressure scanners are all built around the 16 position KPM-1-16 scanner module. These modules have 16 individual sensors that are read by two 24 bit analog to digital converters. The A/Ds read both the pressure and temperature signal from each pressure chip. All of the signal conditioning and analog to digital conversion is done on the module to reduce noise and increase reliability. The digital data is then sent to a central microprocessor which does the digital correction using coefficients stored on each module. This allows for easy configuration by the user for different tests. When a new module is plugged in to a scanner it automatically reads the data from the on board memory and starts to acquire data with no programming by the user needed. It is possible to have modules of different ranges or pressure types (absolute or gauge) on the same scanner. The microprocessor outputs digital data over either Ethernet or RS-485. All of the KMPS series scanners can operate over an extended temperature range of -65° to 255°F (-55° to 125° C).
The KMPS-1 pressure scanner was developed for both the wind tunnel and flight test market. It uses up to 4 KPM modules for a total of 64 channels. It is available with a number of different pressure port configurations for adaptability into existing systems. It also features an optional pneumatic purge.
The KMPS-2 was developed for the flight test market. It features a rugged aluminum enclosures with pneumatic quick connects for easy installation and removal. It also features a heater to prevent icing and an optional motor to activate purging electronically. The KMPS-2 has extra EMI and ESD protection for the flight test environment.
The KMPS-3 was developed for the flight test market. It features rugged aluminum enclosures with pneumatic quick connects for easy installation and removal. It also features a heater to prevent icing and an optional motor to activate purging electronically. The KMPS-3 is water resistant for installation in unprotected environments. Also, it has extra EMI and ESD protection for the flight test environment.
The KMPS-4 was designed for wind tunnel installations. The KPM modules are remote from the main electronics board so that they can be installed throughout a wind tunnel model. They are connected with a thin ribbon cable that can be up to 10 ft long.
The KMPS-6A was designed for use in environments with the potential for explosive gases in the environment (Class I Div II, ATEX Zone 2). It features a purged interior in which a positive pressure is maintained at all times. It also features 64 individual quick connects for easy installation of stainless steel tubing in an industrial environment. The single input line is switched using solenoids to allow routing of control pressures with a minimum number of lines going to the KMPS-6A
All of the KMPS Series of scanners are configured using the Windows Kulite Config Program. This allows for setting of scanning speed, address (IP or RS-485), and other user configurations. Kulite Config also allows for updating of the firmware on the KMPS. Kulite recommends that the firmware be kept up to date to allow for use of all the newest features.
Kulite DAQ allows for data acquisition form multiple KMPS scanners (both Ethernet and RS-485) at the same times. It also allows for calibration of scanners.
