Contactless measurement of temperature at high ambient temperatures. Sturdy and tight stainless steel housings to IP 64. Two-wire 4-20 mA technique in combination with TR 40 / TR 41 transmitter. Sensor heads uncooled up to 125 C ambient temperature. The pyrometers are extremely compact and connected to the transmitter by a teflon cable. Cooling systems are available for ambient temperatures higher than 125 C. An air purging nozzle can be supplied for dusty or damp environments to keep the lens or the cone clean. This technique is a big advantage, for example, if the object to be measured moves or is live. The contactless measuring principle also makes sense if the measured object is a poor conductor of heat (e.g. plastic films or paper) or if the measurement has to be completed quickly. Measuring ranges: 0...2000 C in sub-ranges Power supply via transmitter: 12...30 V DC Smallest measuring field: 5 mm Vibration-proof, no moving parts Interface: HART® protocol Configurable transmitter Cluster / category II2G EEx ib IIC T6 … T4 for application in Ex zone 1 or zone 2 Cluster / category II2G Ex ibD21 T100 105°C/160°C for application in Ex zone 21 or zone 22 The INFRAht R 310/311/312/320 family comprises stationary pyrometers with a remote transmitter for contactless measurement of temperature. Temperature monitoring with ignition protection standard IPL 1, TÜV certificate no. 71332449 Fixing brackets and other accessories are also available. The INFRA TR 40 and TR 41 transmitters integrate the evaluation electronics for the INFRA sensor heads in the INFRAht family (R310/311/312/320). They feature an analogue two-wire interface (4…20 mA). Communication is controlled by a HART® protocol. The transmitters can be used at ambient temperatures up to 70 °C. This results in a very broad range of applications, such as: Thermoforming machines for plastics, Extruders for plastics, Calandering lines for plastic films, Coating machines, Glassworking, Metalworking, Supervision of products on conveyor belts, Monitoring of plant overheating, etc. The TR 40 transmitter is accommodated in sturdy die-cast aluminium housing and has no operator controls or displays. With the R 311 and R 312 types, the infrared radiation is focused on the sensing element by a lens. The R 310 and R 320 types work with a highgloss, gold-plated cone. The TR 41 transmitter is supplied in a plastic housing. It includes an LC display and a configuration keyboard.
