EMA 200

类型	微差压变送器	测量范围	0-20（kPa）
输出信号	4-20（mA）	电源电压	0 - 2 V（V）

Portable,with minb./max. value memoryMeasurement ranges from0 -100 Pa to 0 -200 kPaThis differential pressure gauge has a min./max. value memory and can be used for measuring positive and negative, low- to mid-range differential pressures. Flow-rate measurements are possible through the addition of a pitot tube. The EMA 200 operates by means of inductive displacement transducers that measure the deflection of the membrane of a pressure measurement capsule without making contact.Suitable for battery operation, this durable and easy-to-use instrument can be used for measuring fireplace drafts, monitoring filters, etc., thereby lending itself well to the assembly and maintenance work performed by service technicians in the heating, air-conditioning and ventilation industries. Calibration certificates from either the factory or the German Calibration Service (DKD) are available upon request.DKD calibration certificates are issued by Walcher Meßtechnik GmbH.Technical data:Measuring rangesfrom 0 -200 Pa to 0-20 kPaCan also be calibrated in other unitsLinearity: 0,5 % v.E.Stores min. and max. valueOption 0 - 2 VEasy to operateMedium:Air, all non -aggressive gasesAccessories:DKD-calibration certificatesfactory calibration certificate
