Danfoss RA/RTD thermostatic radiator sensor (operator head), gas-charged, built-in sensor, 16–26 °C setting range, for RTD valves (013G2946)

Danfoss RA/RTD thermostatic radiator sensor, OEM order code 013G2946 — a self-acting thermostatic operator (sensor head): the gas-charged sensing element expands and contracts with room temperature and drives the valve cone through the head, throttling flow to hold the set room temperature with no external power. It clamps onto Danfoss RTD-N radiator valves via the RTD connection (metal nut fixing) and requires no wiring or batteries. Temperature setting range 16 °C to 26 °C; sensing charge gas; housing colour White RAL 9016. The head provides adjustable maximum/minimum temperature limitation and set-point locking with hidden pins under the dial. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 013G2946). OEM P/N 013G2946, EAN 5702420095530. HS 9032.10 (thermostats). Modulates refrigerant flow to the evaporator in response to superheat at the evaporator outlet.

Compatibility

Thermostatic operator head for Danfoss RTD-N radiator valves (RTD valve connection). Built-in type — the sensor reads the air at the valve; do not box in or cover the head, and mount horizontal pipework valves so the head is not above the radiator. Confirm the valve family (RTD) and sensor connection (Metal nut) before ordering; the head fits Danfoss RTD valve bodies only. No power supply required (self-acting). Setting range 16 °C–26 °C.
