Analogue Signal Calculator modules

INT

Integrator Module type 665 The HSE Integrator Type 665 is an analog calculator of the HSE PLUGSYS bus system for universal application. It is used to calculate the area under the curve of an input signal. The module readily provides time or stroke integration of periodic physiological signals or other time-related parameters. Examples for integration: • respiratory minute volume • respiratory tidal volume from the respiratory curve • spirogram • cardiac minute volume • stroke volume from the aortic flow curve • cardiac output c.o. The input signal is supplied either internally through the bus system or at the front from an external instrument. The integrated value is available as an output signal through the system bus and at an additional output on the front panel. In addition the output signal from maximum memory is available on the system bus.

Description
Input	externally through BNC sockets or internally from system bus as selected by switch.
Input voltage	±10 V
Integration time constant	selected in 6 steps: 0.05 / 0.1 / 0.2 / 0.5 / 1 / 2 / 5 / 10 / 20 sec
Integration period	• controlled through the cyclic input signal over one cycle (stroke integration) • time-controlled through a built-in timer, selected in the following steps: 0.5 / 1 /2 /5 /10 / 20 / 30 / 60 / 120 sec • controlled by a trigger signal from the bus system or by pressing a key (RESET key)
Polarity	choice of input signal to be integrated, positive half-wave only or negative half-wave only or both, as selected by switch
Amplitude adjustment	through 10-turn trimmer separately for external and internal input
Analogue indication	through LED bargraph for visual monitoring of the input or output signal; sensitivity ±10 V or ±1 V by pressing the pushbutton "x 0.1".
Signal output	• on the front panel through a BNC socket (±10 V) • through bus connector to PLUGSYS measuring system as selected by links:    a) current integration signal    b) maximum value of the elapsed integration period
Signal output MUX	after pressing the MUX key the current integration signal is switched to the input of an optional digital voltmeter module for precise calibration. The function is self-maintained; the module previously selected is switched off.
Power supply	5 V, 700 mA through connector from PLUGSYS bus system.
Dimensions	module for 19 inch rack, width 8 E (40.5 mm), height 3 U (128.7 mm), depth Europe size (220 mm)
Connector	DIN 41612, 96-pin VG
Weight	330 g
