    Copyright © 2018 Kulite Semiconductor Products, Inc. All Rights Reserved. KMPS-1-64 Manual 2 Theory of Operation The KMPS-1-64 consists of 64 Silicon on Insulator(SOI) piezoresistive pressure sensors mounted onto plates of 16 sensors each. These sensors are then connected to individual pressure inputs via a manifold.

    Copyright © 2018 Kulite Semiconductor Products, Inc. All Rights Reserved. KMPS-1-64 Manual Internal Connections The KMPS-1-64 has an internal purge manifold which allows for the KMPS-1 to be placed either in measure mode or purge/calibration mode by supplying pressure either to the MSR input or PRG input on the two ends of the KMPS (see figure 2).

    Copyright © 2018 Kulite Semiconductor Products, Inc. All Rights Reserved. KMPS-1-64 Manual Temperature Output The temperature is read off of each sensor and then the raw output is converted to temperature using a second order conversion *T + A This data is available for each sensor using the TEmperature command. The UNits command automatically switches the temperature between Fahrenheit and centigrade.

    Copyright © 2018 Kulite Semiconductor Products, Inc. All Rights Reserved. KMPS-1-64 Manual For Ethernet the $ and address can be used or left off. Kulite recommends using the $ and address is the user is using broadcast UDP with multiple scanners otherwise it is redundant with the IP address.

This can be used to find the scanner when the configuration is unknown. 3.2.1 UDP vs TCP Both UDP and TCP can be useful protocols for communicating with the KMPS. TCP allows for direct connection to each KMPS individually allowing for error checking as well as data arriving in the order received with no extra delay.

    Copyright © 2018 Kulite Semiconductor Products, Inc. All Rights Reserved. KMPS-1-64 Manual Pressure Data Rate The data rate of the KMPS acquisition is set using the SAmplerate commands. In general the lowest data rate possible should be used as any pressure fluctuations due to tubing will be eliminated in this way.
