Product Description

Dwyer sealed temperature sensor with 10kΩ Type II Thermistor for industrial process monitoring. Operates from -40 to +125°C in IP66-rated stainless steel 304 probe (5.97 mm diameter). Suitable for suspension or surface mounting in harsh plant environments.

Frequently Asked Questions

What is the Dwyer O-4B temperature sensor used for?

The Dwyer O-4B sealed temperature sensor is used for outdoor air temperature monitoring in building automation systems and ventilated agricultural enclosures. Its IP66-rated stainless steel 304 probe and 10kΩ Type II Thermistor make it suitable for harsh plant environments requiring suspension or surface mounting.

What are the specifications of the Dwyer O-4B temperature sensor?

The Dwyer O-4B features a 10kΩ Type II Thermistor, operates from -40 to +125°C, and has a 5.97 mm diameter stainless steel 304 probe with 3.5 inch length. It is IP66-rated and supports suspension or surface mounting. The removable junction block simplifies installation.

Where to buy the Dwyer O-4B temperature sensor in Singapore?

3G Electric supplies the Dwyer O-4B temperature sensor to Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time on this model (SKU 3G-CBM-02320). We provide local technical support for industrial process monitoring applications.

How to install the Dwyer O-4B temperature sensor?
