JUMO Wtrans T03 RTD Temperature Probe with Wireless Data Transmission and Ex Approval
The JUMO Wtrans T03 RTD temperature probe (also called a transmitter) can be used under consideration of the relevant standards and regulations for portable and stationary temperature measurement in Ex-areas zone 0 (20), zone 1 (21), or zone 2 (22).It is essential to comply with the special conditions of use chapter 1.6 „Special conditions of use "X"“,page 9!The Wtrans T03 is intrinsically safe equipment and suitable for the device group IIB "flammable gases"(a typical gas is ethylene) and for the device group IIIB "non-conductive dust".The measuring insert is equipped with a Pt1000 temperature sensor according to DIN EN 60751, classA in a three-wire circuit. The operating temperature range of the temperature sensor (medium temperature) is -30 to +260 °C.An ambient temperature of -30 to +85 °C is admissible for the JUMO Wtrans T03. The plant manufacturer must take into account the heat input (to be calculated under chapter 1.10 „Heat input through protection tube / protection tube fitting“, page 12) through the protection fitting into the housing. If the deviceis to be used in atmospheres with combustible dust, the maximum surface temperature is T 130 °C. Ina gas atmosphere, the device may be used in temperature class T4.The measured temperature values are transmitted wirelessly to the receiver of the measuring system outside of the Ex-area. The measured values are displayed on the receiver and are available in digital format on the RS485 interface and as analog outputs. Different alarms can be optionally signaled with two relay outputs.The radio frequency of the Wtrans measuring system is 868.4 MHz. This frequency is almost impervious to external interference and allows data to be transmitted even in harsh industrial environments. If the antenna holder for wall mounting (can only be mounted outside the Ex-area) with the 3 m antenna cable is being used for the receiver, the open air range is 300 m.The housing of the JUMO Wtrans T03 is oil-resistant and acid-resistant and has protection type IP67.The protection fitting is made from stainless steel. Only the corresponding JUMO Pt1000 RTD temperature probes with connecting cable for the Ex-area may be connected to the basic type 902930/55... with an M12 × 1 plug connection.Only the approved 3.6 V, 2.2 Ah lithium battery may be used for the voltage supply to the JUMO Wtrans T03.
