YTA110 Temperature Transmitter
The YTA110 is the high performance temperature transmitter that accepts Thermocouple, RTD, ohms or DC milivolts inputs and converts it to a 4 to 20 mA DC signal for transmission. The YTA110 supports either BRAIN or HART communication protocol. The YTA110 in it standard configuration is certified by ¨ TU Vas complying with SIL2 for safety requirement.
Microprocesser-based sensing technology ensures long-term accuracy and high reliability. T/C: 0.1% of reading or 0.1°C per year, whichever is greater at 23 2°C. 5 Year Stability RTD: 0.2% of reading or 0.2°C, whichever is greater at 23 2°C. T/sC: 0.4% of reading or 0.4°C, whichever is greater at 23 2°C. RFI EffectTested per EN 50082-2, field intensity up to 10 V/m. Power Supply Effect ±0.005 % of calibration span per volt Vibration Effect 10 to 60 Hz 0.21 mm peak displacement 60 to 2000 Hz 3G Position Effect None
Dual-compartment housing realizes high resistance capability to harsh environments, and YTA110 has SIL2 capability for safety requirement.
Variety of sensor inputs
The type ofsensor input is user-selectable from thermocouples (T/C), RTDs, ohms, or DC milivolts.
BRAIN or HART® communication protocol is available. The insturment configuration can be changed by the user with using the BT200 or HART communicator.
Continuous self-diagnostics capability ensures longterm performance and lower cost of ownership.FUNCTIONAL SPECIFICATIONS Input
Input type is selectable: Thermocouples, 2-, 3-, and 4-wire RTDs, ohms and DC milivolts. See Table 1. on page 3. Span & Range Limits See Table 1. on page 3. Input signal source resistance (for T/C, mV) 1 k or lower Input lead wire resistance (for RTD, ohm) 10 per wire or lower Output Two wire 4 to 20 mA DC. Output range: 3.68 mA to 20.8 mA BRAIN or HART ® protocol issuperimposed on the 4 to 20 mA signal. Any single value from the followings can be selected as the analog output signal. Sensor 1, Terminal Temperature. Also, up to three of the above values can be displayed on LCD display or read via communication. Isolation Input/Output/GND isolated to 500 V DC
LCD display with bargraph
The LCD display provides both a digital readout and percent bargraphsimultaneously.
