PYS3428

Pyroelectric detectors for GAS MONITORING Pyrodetectors For Gas Monitoring And Measuring PYS 3228, PYS 3428 – Dual-Channel Pyros Applications Gas Sensing and Monitoring Features and Benefits TO-5 metal housing Dual Channel Output Each Channel with individual Filter Window Selection of narrow band pass filters Thermal Compensation option Product Description As the successor to the LHi 814 series, the PYS 3x28 Dual-Channel detectors have become standard for gas sensing applications, with two, individual 1.5 x 1.5 elements, and with additional temperature compensation. They are available with a range of narrow band pass filters, as specified on page 4, in combination with a reference filter. The same features are included with the PYS 3428, which offers additional EMI protection by internal capacitors. PYS 3228 PYS 3428 PYS 3228 and PYS 3428 Parameter Operation Voltage Responsivity, min.
