The leads that supply power also carry the current signal. Output: Calibration Accuracy: Transmitter Linearity: Physical: Operating Environment: Storage Environment: Ambient Temperature Effects: Warm-up Drift: Supply Voltage: Input Voltage Effect: Maximum Load Resistance: Note: Transmitter circuit board only, Room Air housing and RTD sold separately. ![]() System Integration: Zero and Span Adjustment: Maximum Output Current: Power Connections: Sensor Connections:ġ00 ohm platinum RTD, 0.00392 ohm/ohm/☌ TCR, 100 ohm platinum RTD, 0.00391 ohm/ohm/☌ TCR, 100 ohm platinum RTD, 0.00385 ohm/ohm/☌ TCR, 1000 ohm platinum RTD, 0.00385 ohm/ohm/☌ TCR 1000 ohm platinum RTD, 0.00375 ohm/ohm/☌ TCR 4 to 20 mA DC over specified range, limited to 30mA maximum. Printed circuit board designed to mount inside the S470 series thermostat housing with RTD 32° to 122☏ (0° to 50☌), non-condensing. ± 0.001% of span per volt from 8.5 to 35 VDC. The maximum allowable resistance of the signal-carrying loop, including extension wires and load resistance, is given by this formula: Rloop max = (Vsupply-8.5)/.02 amps. For example, if the supply voltage is 24 VDC, the loop resistance must be less than 775 Ω. Output “High” (22-28mA) with sensor open. Output “Low” (3.3-3.7mA) with sensor shorted. Screw terminals, non-polar (connect either way). Installation Locate the Temptran near the RTD, in an area where the ambient temperature stays between the temperature range of the output. Connect the Temptran as shown in the wiring diagram below. The transmitter’s power and RTD connections are designed for non-polar hook-up, so polarity is not important. The maximum DC supply should not exceed 35 VDC. For the RTD, good connections are a must, a few ohms of resistance in the connection could cause an error of several degrees. The Temptran has been factory-calibrated to its marked temperature range or to a specific RTD, do not change its Zero or Span adjustments. Power Supply DC power supply requirements are determined by the transmitter’s minimum voltage requirement and voltage drop across the load resistor and installation lead wires. Example: The transmitter requires 8.5 Volts minimum. A typical 250 ohm load resistor drops 5.0 Volts 20 mA. Allowing a margin of 0.5 Volts for the supply permits 25 ohms of lead wire resistance for remote installation. Set point adjustment and/or manual override buttons are available on wall mount sensors.Ī plug-in display that can be universally applied to all MBS, AKS and MBT transmitters with a 4–20 mA output and a plug connection according to EN 175301-803-A.Totaling these, we get a minimum power supply requirement of 14 VDC. The duct mount and outside air mount sensors come standard with sintered filters to protect the sensor from particulates. The stylish housing is well vented to provide air flow across the sensor to improve measurement accuracy. Wall Mount Temperature Transmitter is a compact economical sensor for the building automation market space. ![]() It can be used for pressures up to 100 bar. Temperature measurement of liquid and gaseous media in Threaded mount temperature transmitters is used for Head mount temperature transmitter to convert TC/RTD/Linear volts/Linear resistance input signals into a scalable 4 to 20 mA analog output signal. ![]() ![]() Their compact designs, along with dual channel options, help accommodate multiple temperature measu Temperature Transmitters - DIN Rail MountĭIN rail mounted temperature transmitters offer high measurement accuracy, stability and reliability over a wide range of process and ambient temperatures. Temperature transmitter devices convert the input signal from a wide range of temperature sensors, such as resistance thermometers, thermocouples, and potentiometers, into a standardized analogue or digital output signal.
