FOR USE IN HAZARDOUS LOCATIONS
An intrinsically-safe humidity transmitter, the HMP
260 EX is designed for use in potentially explosive
environments. Hospitals, chemical and petrochemical
industries, as well as many processing industries
should use this transmitter where substances, such as
solvents and explosive dusts, present such a hazard.
The HMP 260 EX can even be used in hydrogen, one
of the most easily ignitable gases. Its classification
means that it can be used in areas where an explo-
sive gas atmosphere is continuously present, or is
present for long periods of time; and that protection
is maintained with up to two components or other
faults. When used in environments where explosion
protection is essential, the HMP 260 EX must always
be connected to the power supply through the zener
barriers.
FAST AND RELIABLE
Fast, stable, and accurate, the HMP 260 EX has been
fully temperature compensated over the entire
measurement range of 0...100% RH in temperatures
from -4 to +140 °F (-20°C to +60°C). It utilizes
Vaisalas HUMICAP
®
capacitive thin-film humidity
sensor which has proven successful in many de-
manding industrial applications with accuracies of up
to ±2%RH. Furthermore, the sensor is not affected by
most chemicals and dust particulates.
