Signal amplifier Trig-Tek™ 203PC-1

chargedigitalrack-mount

The Trig-Tek™ 203PC-1, -2 charge amplifiers operate with high temperature accelerometers where pyroelectric effects may be encountered Product Information The Trig-Tek™ 203PC-1 and 203PC-2 cover the frequency range from 3 Hz to 40,000 Hz. They double-integrate the 10 g acceleration output signal to provide velocity and displacement outputs. A four-position thumb-wheel sensitivity control in conjunction with a three-position toggle switch accommodates pickups hav- ing sensitivities from 0.100 to 199.9 pC/g, mV/g, or mV/ips. A “Mode” switch selects “pC/g” (“AA,” “AV,” or “AD”), “mV/g” (“AA,” “AV,” or “AD”), or “Vel” (VV or VD). The DC output switch selects “X1” or “X10” for g’s, ips, or MILs at the “DC Output.” An external “Cal” signal can be selected by a front panel switch or by the “Cal” control input (rear panel). A Low-Pass Filter has 100 Hz to 19.9 kHz cutoff frequencies in 100 Hz steps, and a High-Pass filter has 1 to 999 Hz cutoff frequencies in 1 Hz steps. A digital front-panel meter displays selec- table Full Scale (FS) levels of “10,” “20,” “50,” “100,” “200,” or “500” g’s Pk or “1,” “2,” “5,” “10,” “20,” or “50” ips or MILS Pk. The 203PC is packaged as a plug-in mod- ule. Available are a single-module chassis and a six-module chassis When “mV/ips” is selected, the amplifier will operate with ICP-type velocity pickup with the “Curr-On” or with a standard velocity pickup with the “Curr-Off.” A “DC Output” switch permits selection of either “X1,” “X10,” “10 mV/g,” or “100 mV/ips” or MIL at the “DC Output.” An “External Cal” signal can be selected by the front panel “Mode”/”Units” switch or by the “Cal” control input (rear panel).
