The YTA70 delivers all the benefits found in the YTA50 while adding HART digital protocol communication. The HART protocol allows you to conveniently configue the transmitter using the latest FDT/DTM technology. The YTA70 is the choice for all your control applications.
Compact and lightweight head-mounted transmitter (~0.11 lb as per distributor). Input lead-wire resistance: for RTD, up to 50 Ω per wire is configurable (with some impact on accuracy). Good for control systems where digital diagnostics (via HART) are valuable. Useful in applications with various sensor types — thermocouples, RTDs, or custom sensors. Ideal for tight mounting spaces — head-mounted design saves room. Suitable for hazardous areas (IS versions) because of intrinsic safety options. Can be used in older or modern control systems (4–20 mA analog + HART).
4-20 mA DC analog output.
Digital communication via HART: either HART 5 (-E version) or selectable HART 5 / HART 7 (-J version)
Supports a variety of sensor inputs — 17 input types according to spec.
Thermocouples (T/C)
RTDs (2-, 3-, and 4-wire)
Ohms (resistance sensors)
DC millivolt signals
Head-mount (DIN Form B) design.
Also supports DIN-rail mount (with suitable adapter) per supplier information.
Operating supply voltage: 8–35 V DC.
For digital (HART) communication, supply 13.8–35 V DC.
Load resistance: up to a value determined by supply voltage (see spec sheet).
Cold-junction compensation (for thermocouples): ± 1 °C typical.
Power-supply effect: ± 0.005% of full scale per volt.
Ambient temperature effect is specified (dependent on option codes).
Sensor burnout (“burnout”) feature: supports NAMUR NE-43 (upscale, downscale, or configurable).
Response time (damping) is configurable: from 1 up to 60 seconds.
Ambient temperature limits: −40 °C to +85 °C (varies by model)
Versions available with IECEx, ATEX, and FM intrinsically safe / non-incendive approvals (e.g., suffix /KS2, /SS2).
Microprocessor-based design for stable performance.
HART protocol allows configuration via FDT / DTM tools.
HART 7 (if selected) supports long tag (up to 32 characters), enhanced burst mode, event notification, command aggregation.
