{"product_id":"trmb-raum-widerstandsthermometer-rwt","title":"TRMB Room Resistance Thermometer (RRT)","description":"\u003cp\u003eThe \u003cstrong\u003eTRMB\u003c\/strong\u003e is a room resistance thermometer with screw terminals, manufacturer type Müller \u003cstrong\u003eRWT\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt is wall-mounted and measures the air temperature in the room – in HVAC and cold storage applications. The data sheet does not mention a process connection or system pressure: The sensor measures the room air, the mounting position is arbitrary, and the protection class is \u003cstrong\u003eat least IP 66\u003c\/strong\u003e. Connection is not made via a plug, but via \u003cstrong\u003escrew terminals up to 2.5 mm²\u003c\/strong\u003e in the housing; the cable gland (\u003cstrong\u003eM12, M16 or M20x1.5\u003c\/strong\u003e) is set according to customer specifications.\u003c\/p\u003e\n\u003cp\u003eFour housings are available, allowing the design to adapt to the mounting location: three made of aluminum die-cast alloy in gray RAL 7032 – \u003cstrong\u003eAK082\u003c\/strong\u003e 80 × 125 × 57 mm, \u003cstrong\u003eAK081\u003c\/strong\u003e 75 × 80 × 57 mm, \u003cstrong\u003eAK061\u003c\/strong\u003e 64 × 58 × 36 mm – and \u003cstrong\u003e1503\u003c\/strong\u003e 120 × 80 × 58 mm made of ABS; weights range from approximately 225 to 500 g. The sensor tube is made of stainless steel \u003cstrong\u003e1.4571\u003c\/strong\u003e or Delrin POM.\u003c\/p\u003e\n\u003cp\u003eMeasuring elements include \u003cstrong\u003e1× or 2× Pt100\u003c\/strong\u003e, \u003cstrong\u003e1× or 2× Pt1000\u003c\/strong\u003e, \u003cstrong\u003e3× Pt100\u003c\/strong\u003e or a thermocouple \u003cstrong\u003eType K\u003c\/strong\u003e, in 2-, 3- or 4-wire configuration and in classes \u003cstrong\u003eA, B and AA (B1\/3 DIN)\u003c\/strong\u003e; the range extends from \u003cstrong\u003e-50 … +100 °C\u003c\/strong\u003e. Without a transmitter, the resistance thermometer is connected directly to the terminals – the output is then the resistance or thermovoltage signal itself, and the sensor does not require a power supply. With a transmitter, \u003cstrong\u003e4 … 20 mA\u003c\/strong\u003e and \u003cstrong\u003e2 … 10 V\u003c\/strong\u003e are available, depending on the type, with 0.3% of the range or ±0.1% of the full scale value.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note before ordering:\u003c\/strong\u003e Two of the four housings do not accommodate a transmitter – it is only intended for AK082 and 1503, but the combination with AK061 and AK081 is not blocked in the ordering key. The sensor tube is not dimensioned: Only material and position can be selected; length and diameter must be requested from the manufacturer. The permissible ambient temperature depends on the housing and the transmitter: Die-cast aluminum -50 … +100 °C, plastic -50 … +85 °C, with transmitter in both cases only \u003cstrong\u003e-40 … +85 °C\u003c\/strong\u003e. The transmitters are proprietary products: TP-RTD, DTW, TH-RTD, and DTW Ex only work with resistance thermometers; TP-TC only works with thermocouples. A CE mark and a declaration of conformity are not available; the marking \u003cstrong\u003eII 1G Ex ia IIC T6 … T4\u003c\/strong\u003e applies only to the DTW Ex transmitter, not to the sensor or the housing.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eFour housings: die-cast aluminum AK082, AK081, AK061 or ABS 1503\u003c\/li\u003e\n\n\u003cli\u003ePt100, Pt1000, 3× Pt100 or thermocouple Type K\u003c\/li\u003e\n\n\u003cli\u003eClasses A, B and AA (B1\/3 DIN), 2-, 3- or 4-wire, -50 to +100 °C\u003c\/li\u003e\n\n\u003cli\u003eTransmitter as an option, 4 … 20 mA or 2 … 10 V\u003c\/li\u003e\n\n\u003cli\u003eScrew terminals up to 2.5 mm², cable gland M12 to M20x1.5\u003c\/li\u003e\n\n\u003cli\u003eSensor tube made of 1.4571 or Delrin POM, protection class at least IP 66\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356931891526,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TRMB_produkt_c84c65f8-4488-4b9d-b9a7-d8bd4fcbd875.webp?v=1789243718","url":"https:\/\/octogon-sensors.com\/en\/products\/trmb-raum-widerstandsthermometer-rwt","provider":"octogon GmbH","version":"1.0","type":"link"}
