{"product_id":"trmc-raum-klima-sensor-rks","title":"TRMC Room Climate Sensor (RCS)","description":"\u003cp\u003eThe \u003cstrong\u003eTRMC\u003c\/strong\u003e is a room climate sensor for temperature and relative humidity, manufacturer type Müller \u003cstrong\u003eRKS\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt is wall-mounted, combines two measured variables in an aluminum housing and displays them on site – designed for refrigeration systems on ships, for cold rooms and for building services. The housing is an \u003cstrong\u003ealuCase AC092 with 160 × 90 × 60 mm\u003c\/strong\u003e made of die-cast aluminum, weighing a maximum of \u003cstrong\u003e1.1 kg\u003c\/strong\u003e; connection is via \u003cstrong\u003escrew terminals up to 2.5 mm²\u003c\/strong\u003e and three cable glands \u003cstrong\u003eM16x1.5\u003c\/strong\u003e. The protection class is \u003cstrong\u003eIP 65\u003c\/strong\u003e without and \u003cstrong\u003eIP 63\u003c\/strong\u003e with humidity sensor, which sits behind a PTFE filter.\u003c\/p\u003e\n\u003cp\u003eWhere otherwise two devices would be wall-mounted, here there is one: transmitter and display are not accessories, but part of the order key. The display is \u003cstrong\u003e4-digit and 7-segment\u003c\/strong\u003e, 8 mm high, its range of \u003cstrong\u003e-999 … 9999\u003c\/strong\u003e digits is programmable.\u003c\/p\u003e\n\u003cp\u003eTemperature is measured by \u003cstrong\u003e1× or 2× Pt100\u003c\/strong\u003e in 2-, 3- or 4-wire circuits in classes \u003cstrong\u003eB, A, B 1\/2 DIN and B 1\/3 DIN\u003c\/strong\u003e, the protective tube is made of stainless steel \u003cstrong\u003e1.4571\u003c\/strong\u003e; the humidity sensor measures \u003cstrong\u003e0 … 100 % RH\u003c\/strong\u003e with \u003cstrong\u003e±2 % RH\u003c\/strong\u003e from 5 … 95 % RH at 10 … 40 °C. The two measured variables take separate paths: Humidity is output directly as \u003cstrong\u003e4 … 20 mA\u003c\/strong\u003e, \u003cstrong\u003e0 … 10 V\u003c\/strong\u003e or \u003cstrong\u003e2 … 10 V\u003c\/strong\u003e, for temperature a transmitter \u003cstrong\u003eTAP2L or TMRO\u003c\/strong\u003e can be selected. The device is powered by \u003cstrong\u003e24 … 30 VDC\u003c\/strong\u003e; limit contacts are not mentioned in the data sheet.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note before ordering:\u003c\/strong\u003e With the humidity sensor, the protection class decreases from IP 65 to IP 63 – the PTFE filter must allow air to pass through, so the version with humidity is no longer protected against jet water. The humidity sensor requires air movement: at least 1 m\/s across the sensor at the current output and 0.5 m\/s at the voltage output; measurement in still air is not guaranteed. The source contradicts itself regarding the measuring range: feature list \u003cstrong\u003e-40 … +80 °C\u003c\/strong\u003e, data table of the temperature sensor -50 … +100 °C – the smaller value is the safe one; the display only operates from 0 to +80 °C. The power supply is also stated differently twice in the sheet: feature list 24 VDC, order key 24 … 30 VDC – we use the value of the key. The protective tube is designated 1.4571, but not dimensioned; length and diameter must be requested. Long-term drift and calibration interval of the humidity sensor are not documented, nor are a CE mark and explosion protection.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eTemperature and relative humidity in one device\u003c\/li\u003e\n\n\u003cli\u003eHumidity 0 … 100 % RH, ±2 % RH from 5 to 95 % RH\u003c\/li\u003e\n\n\u003cli\u003e1× or 2× Pt100, classes B to B 1\/3 DIN, measuring range -40 to +80 °C\u003c\/li\u003e\n\n\u003cli\u003eSeparate outputs, humidity as 4 … 20 mA, 0 … 10 V or 2 … 10 V\u003c\/li\u003e\n\n\u003cli\u003eDisplay 7-segment, 4-digit, 8 mm, -999 to 9999 digits\u003c\/li\u003e\n\n\u003cli\u003eAluminum housing 160 × 90 × 60 mm, maximum 1.1 kg, IP 65 – with humidity sensor IP 63\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356932383046,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TRMC_produkt_b8424803-bcdb-4ec4-b028-a9bbf5af8f91.webp?v=1789243718","url":"https:\/\/octogon-sensors.com\/en\/products\/trmc-raum-klima-sensor-rks","provider":"octogon GmbH","version":"1.0","type":"link"}
