DescriptionOMEGA’s PCL341 and PCL342 set a new standard for handheld pressure calibrators. Both models have internal, isolated, stainless steel pressure sensors with 0.025% FS accuracy. For greater measurement capability, an external connection supports all OMEGA PCL-PM Series pressure modules. A Pt100 RTD input allows temperature readings accurate to 0.1ºC (0.2ºF). (One Pt100 RTD probe comes with the “-KIT” models.) The PCL341 and PCL342 measure 4 to 20 mA loop current and up to 30 Vdc. An internal 24 V loop power supply can power a transmitter under test. The PCL342 can display up to 3 measurements simultaneously—for example, 3 pressure measurements. The ability to display 2 pressure readings along with an RTD temp makes the PCL342 ideal for gas flow calibration (custody transfer) applications. The PCL341 is available in 9 ranges from 5 to 10,000 psig. The PCL342 comes in 2 standard ranges—15/1500 psi or 30/3000 psi—or the user can select 2 ranges from 5, 15, 100, 300, 500, 1000, 3000, 5000, or 10,000 psig. It also comes in a kit, which includes the PCL342 pressure calibrator, Pt100 RTD probe, batteries, operator’s manual, NIST-traceable certificate, test leads, and hard-sided carrying case.
