Details

These ready to use temperature or humidity sensors with 4-20mA output are designed for use in industrial applications.

A family of products capable of measuring Temperature, Humidity, pressure with 4-20mA output.

Boxed with IP rating of IP65 these sensors measure temperature and/or humidity and are readily connected to existing systems that can accept 4-20mA measurements.

Moreover the output range can be adjusted by simply connecting these sensors to a PC, using our SP003 USB cable. It is also possible to adjust this range at the factory by simply stating what range you require in your order.

Some members of the family come with integrated sensors, whereas the others can accept external Pt1000 sensors with connector blocks provided for ease of connection.

LCD display allows the live reading of the data. The temperature can be displayed in Degrees Celsius and Fahrenheit (user selectable.

Delivered with traceable calibration certificate, these sensors are reliable, durable and accurate, are easily added to your existing system and, due to high design values have long term stability.
