1. Hlavní funkce

1.1 má dva kanály, každý kanál může měřit a zobrazovat amplitudu vibrací.

1.2 Má 4 dvoukanálové přepínání ovládající signály. Pomocí miniaturního vysokovýkonného relé je maximální spínací napětí 440VAC / 125VDC, maximální spínací proud je 16A, maximální spínací výkon je 4000VA, mechanický tlakový odpor je 10 miliónkrát. Prostřednictvím nastavení dolní mezní hodnoty alarmu, nastavení horní mezní hodnoty alarmu, nastavení zpoždění alarmu a nastavení dolní mezní hodnoty nebezpečí, nastavení horní mezní hodnoty nebezpečné hodnoty, nastavení zpoždění nebezpečí, příslušná akce, když amplituda vibrací dosáhne přednastavené hodnoty , přepne relé do provozního stavu.

1.3 Dual 4 ~ 20mA isolation high precision current transmission output, with high precision voltage reference inside, 18 digits precision voltage drive chip, high precision and low drift

operational amplifier, guarantee the accuracy of the output reach 0.01%. By the main range lower limit setting and main range upper limit setting of the menu item, divide it into the corresponding

current interval of 4 ~ 20mA accurately, so that improves the accuracy of output signal. Calibrate the lower limit and upper limit of current loop by current meter, then demarcate the linearity of 4 ~ 20mA more accurate.

1.4 Zařízení má hlavní displej rozsahu, procentuální zobrazení, sloupcový graf, zobrazení proudu přenosu. Pro zákazníky je výhodnější, rychlejší a přesnější provést kalibraci v aplikaci na místě.
