Temperaturfühler Thermoelement

ΔSBWSeriesTemperaturetransmittersandthermocouple/RTDassemblieswithtransmitter The transmitter outputs 4 20 mA signal, proportional to the measured temperature, to displayers, recorders or computers. It is embedded in the connection head of a thermocouple or RTD assembly.The transmitters feature high accuracy, low power consumption, wide ambient temperature range and high reliability. Owing to the silicone rubber sealing they are vibration-resisting, humidity-resisting and suitable for use in severe working conditions.The transmitters have functions of linearization and temperature compensation of reference junction.The transmitter can be used as a module in other applications.SpecificationsInput: Pt100 (for resistance thermometer)For transmittersB, S, R, N, K, E, J, T (for thermocouple)Output: 4 20 mA dc linear with temperature.Accuracy: ±0.2% FS, ±0.5% FSLoad resistance: Load limit shall be:RLmax = 50 × (Vmim – 12)The load resistance can be selected in the range of 0 600Ω when the voltage is 4V. The nominal load resistance is 250Ω.Power supply: Nominal voltage: 24V; Mim. voltage: 12V; Max voltage: 35VFor thermocouple/RTD assembly with transmitterTwo-wire or four-wireAccuracy: Δ = Δt + ΔbHere It is the tolerance of the thermocouple or RTD.Δb is the accuracy of the transmitter.Working conditionAmbient temperature: -25°C 80°C ( not higher than 70°C in hazardous area)Relative humidity: 5% 95%RHMechanical vibration: f≤55Hz, amplitude 0.15 mmNo corrosive gases in atmosphereTemperature coefficient: ≤0.05%/°C The thermocouple elements and resistance elements are sheathed.Protection tubes are made of two kinds of stainless steel.Connection head is made of aluminum alloy and is water-proof. Its protective class is Grade IP54.Transmitter is a disassembled unit. Its circuit board is sealed inside the case by silicone rubber.
