Pressure transducers DMU 02 Vario (flush)

Transcription

1 Process engineering (flush) Ideal for hygienic processes Connection technology with numerous versions Extremely resistant to shock, pulsation and vibration Best dynamic pressure resistance at high load changes Measuring cell welded without seals Zero correction via magnet A A A Page 709 Page 710 Page 711 Application Description For electronic pressure measurement in mechanical and plant engineering applications, gas applications and medical technology. With flush diaphragm, the pressure transducers are also suitable for use with viscous, highly viscous or crystallising media. convert physical pressure into an electrical signal proportional to the pressure. uses a piezo-resistive poly-silicon thin film measuring cell. is available in a virtually unlimited number of versions. All standard and customer-specific connections can be connected to the electronic precision measuring system. All standard electrical connection types are available. The zero point can be corrected from the outside via a permanent magnet after voltage has been supplied and within a given time window. Technical specifications Measuring accuracy Deviation from the characteristic curve according to IEC limit point calibration (non-linearity, hysteresis, repeatability): <±0.3 % FSO Measuring ranges Relative pressure: -1/0 to -1/+24 bar 0/1 bar to 0/600 bar Overpressure safety 250 bar at least 2 x FS (burst pressure at least 3 x FS) > 250 bar at least 1.5 x FS (burst pressure at least 2 x FS) Material Housing: 304 Pressure connection: 316 L Seal: Without Pressure transmission liquid Multi-grade oil, FDA-compliant Supply voltage DC 9 32 V Output signal 4 20 ma, 2-wire Load UB 4 20 ma < UBmin 0.02 A Operating temperature range Medium: -10/+5 C Ambient: -10/+105 C Storage: -10/+5 C Temperature error band In compensated range 0/70 C < 1.5 % FSO/10 K Dynamic characteristics Response time < 20 ms Process connection G½B DIN 3852 A with O ring (FBO); Clamp (CP); dairy fitting (MR); Varivent (VT); NEUMO BioControl (BC); Flange connection (FT) Current input < 25 ma Electrical protection Short circuit proof and protected against reverse polarity Electrical connection/degree of protection Connector and junction box as per ISO 4400 (DIN A), IP 65 CE conformity (EMC) EMC Directive 2004/108/EC i See page 532 for dimensions.
