A low-profile room sensor using a stable platinum RTD element to measure cleanroom temperature without obstructing routine wall cleaning.
- Platinum RTD Stability
- Low-Profile Clean Housing
- Fast Room-Air Response
- Passive or Active Output
مقدمة المنتج
The cleanroom temperature sensor houses a platinum resistance element behind protected ventilation slots that expose it to representative room air. A smooth, compact enclosure minimizes horizontal ledges while allowing enough airflow for responsive measurement. Passive resistance outputs connect directly to compatible controllers, while active versions provide standardized voltage, current or digital signals. Remote electronics or sealed terminal arrangements can be selected for areas where regular wipe-down cleaning is required.
الخصائص الرئيسية
Protected ventilation paths balance air response with resistance to casual contact.
A shallow white enclosure reduces visual obstruction and exposed ledges on cleanroom walls.
Passive and active output choices match DDC, PLC and monitoring-system input types.
مخاوف المنتج للعملاء
A room temperature sensor must sample representative air while avoiding heat from the wall, direct drafts and frequently touched locations.
The sensor reads warmer because its electronics heat the sensing element.Separated low-power electronics and airflow around the RTD reduce self-heating error.
Wall conduction biases the reading after adjacent-space temperature changes.An internal stand-off and ventilated housing reduce direct thermal coupling to the wall.
Cleaning cloths catch on deep vents and protruding parts.A shallow housing with protected side slots keeps the exposed profile simple.
The controller requires a different sensor resistance or signal type.Selectable passive RTD and active transmitter versions support common control inputs.
