![]() Pulse output: Consumption quantity counter (value remains available after reset or power cut due to non-volatile memory), value 1 or 10 m 3, pulse length 0.02 to 2 s, 24 V DC level Output type: 4 to 20 mA (4-wire) freely scalable between zero and measuring range end Response time: <0.1 seconds (for damping parameter = 0), delayable via operating menu (0 to 1 second) Sensor: Thermal, glass-coated ceramic sensor (calorimetric measurement procedure) Measuring range (1:300) *: 2.3 to 700 m 3/hĪccuracy (normal volume flow): For compressed air quality classes (ISO 8573: particles-humidity-oil) 1-4-1: ☓% of measurement value ☐.3% of final valueįor compressed air quality classes (ISO 8573: particles-humidity-oil) 3-4-4: ☖% of measurement value ☐.6% of final value Testo 0555 6454 Specifications Measurement Parameters This transmitter has an exactly known diameter – and is adjusted directly according to norm volume flow, and not flow velocity! As shown in the illustration, even normed pipes can vary in interior diameter to such a degree that inaccuracies of up to 33% are possible. Commercially available penetration probes measure the flow velocity and calculate the volume flow by multiplication with the cross-section area. no flange recesses etc.) Many clever details in the design of this transmitter ensure that the flow profile remains constant and that an optimum of accuracy can be achieved.Defined interior diameter and volume flow adjustment for highest accuracy especially in small diameters, the exact knowledge of the interior diameter plays a deciding part in achieving accurate measurements of norm volume flow. In this transmitter, not only are the inflow and outflow pipes integrated, they also have completely even surfaces (i.e. ![]() With penetration probes, a tilt out of the vertical of 5° already leads to a measurement inaccuracy of 5%. Superior design from the sensor to the housing in contrast to the penetration probes used by competitors, the sensor in this transmitter has a position in the pipe which is exactly known and always the same. The thermal, glass-coated ceramic sensor offers robustness at the same time as fastest reaction times. The built-in inflow and outflow pipes allow optimum accuracy. Length measurement pipe: 475 mm (shortened measurement stretches)įor all important diameters: the compressed air counter transmitter in four diameter sizes, this transmitter offers a compact design coupled with integrated high-performance technology, which provides all necessary signal outputs.Measuring stretch: Thread (both sides)/material: R2.Built-in inflow and outflow pipes allow optimum accuracy. ![]() Superior design from the sensor to the housing.Offers robustness at the same time as fastest reaction times.Compact design coupled with integrated high-performance technology. ![]()
