Caratteristiche principali
Quick and reliable detection of carbon dioxide in the ambient air: the microprocessor-based Polytron 8720 transmitter, which contains a new, innovative IR sensor with drift-free optics, can also be integrated into your digital fieldbus system, thus providing additional diagnostic functions.
Simple instrument management thanks to digital communication
?With its HART® ability, the Dräger Polytron 8720 allows remote access using the Dräger PolySoft 8000 software for the quick and convenient evaluation of the instrument status. Integration in existing management systems (e.g. PactWare) is also possib … Maggiori informazionile using DTM. In addition, fieldbus systems such as Foundation Fieldbus or Profibus are supported by corresponding interfaces.
Proven – and still getting better: Dräger measurement technology
?Dräger has been developing and manufacturing sensors and gas detectors for industrial use for more than 40 years. And with each new device generation, we drive our measurement technology a bit further. With the Polytron 8720, you will definitely ben … Maggiori informazioniefit from this experience and power of innovation. Its DrägerSensor is based on an open, double-compensated optical infrared system.
Stesso design, stessi principi di funzionamento
Il rilevatore Polytron 5200 appartiene alla serie Dräger Polytron 5000. Tutti i trasmettitori di questa serie hanno lo stesso design e la stessa interfaccia utente. Questo consente un impiego uniforme con esigenze ridotte di formazione e manutenzione … Maggiori informazioni.Il display retroilluminato indica chiaramente le informazioni di stato, con accesso rapido alle funzioni tramite una comoda chiave magnetica. Durante il normale funzionamento viene visualizzata la concentrazione di gas misurata e l'unità di misura. Tre LED colorati (verde, giallo e rosso) forniscono informazioni supplementari di allarme e di stato.
Optional: Two mounting sets for easy flange-mounting
?The housing has four mounting holes. Two different mounting sets are available for installing the Polytron 8720: a duct-mount and a pipe-mount set. This means that the transmitter can be easily installed anywhere – e.g., on a smooth wall, a pipe or … Maggiori informazionian exhaust duct.
Additional advantages
- ?Easy and cost-effective: one-man calibration
- Available as flameproof or increased safety version
- Aluminium or 316 L stainless steel housing for the most extreme industrial conditions
- Extremely user-friendly software thanks to a minimum number of men … Maggiori informazioni
Efficient, stable and robust – Dräger PIR 7200
?With short response times and a high signal stability, the Dräger PIR 7200 offers a high degree of safety – thanks to an extremely light-efficient optics with a 4-beam signal-stabilizing system. Another advantage is its low sensitivity to dust, dirt … Maggiori informazioni deposits or insects on the optical surfaces in the measuring cuvette, while offering a drift-free output signal and longer maintenance intervals.
Optional: Three relays for controlling external equipment
?On request, the Dräger Polytron 8720 can be supplied with three integrated relays. This enables you to use it as an independent gas detection system with two arbitrarily adjustable concentration alarms and one fault alarm. Audio alarms, signal light … Maggiori informazionis, or similar devices can, thus, be controlled locally – without an additional cable between the transmitter and a central controller. The sensor signal can be evaluated using the 4 to 20 mA signal.
