STD190, 290, 591
The STD190, STD290, and STD591 sensors are delivered as complete units,
comprising a junction box and a cable on which four sensors are located at 1 metre
(3.3 ft.) intervals. The distance from the first sensor to the junction box is 2 metres (6.6 ft.).
The sensors contain four thermistors and is a mean value temperature sensor.
The sensor is used for temperature measurement in air ducts. It is intended for
mounting on to a grid or on wires suspended across a duct.
Accuracy See Appendix A: Tables D, E
STD300
STD300 is an electronic temperature transmitter that converts the temperature
measured into an electric current signal 4-20 mA. The transmitter is delivered as
a complete unit, comprising a stainless steel immersion well, the sensing element
and an amplifier, mounted in a housing.
The transmitter is intended for immersion installation and is used for temperature
measurement in air ducts. The transmitter shall be connected with a 2-wire cable,
which serves both as power supply and for signal transmission.
