Description
The insertable resistance thermometer with measurement insert 1x Pt1000 according to DIN EN 60751 (tolerance class A) is designed in three-wire technology and determined for temperatures from -30 to +260 °C. The measured values are transmitted wireless, via radio to the suitable Wtrans receivers via an integrated Wtrans transmitter, displayed there and are available in digital form on the RS485 interface as well as as as an analogue output. The resistance thermometer is therefore generally suitable for applications where a high wiring effort has to be avoided or is not possible at all. A receiver variant can signal different alarms at two relay outputs. The transmitter electronics of the resistance thermometer are vibration-proof in the oil and acid-resistant housing, the ambient temperature of which may be in the range of -25 to +125 °C. The protection class is IP67. A long-life lithium battery of 3.6 V is used for the power supply. The radio frequencies of the Wtrans measuring system (868.4 MHz) are largely insensitive to external interference and allow transmission even in harsh industrial environments. If the antenna wall bracket is used on the receiver side with the 3 m long antenna line, the range is 300 m. in free field The 4.0 mm thick stainless steel tube is equipped with a centered probe tip (angle 25°). Insertion length is 100 mm. A setup program is available as an accessory for the simple configuration and parameterization of the Wtrans measuring system on the PC. Optionally, you can use the OnlineChart function to record readings to your PC.
