The
MIST is a RTD sensor build with a transmitter hermetically sealed in
a stainless steel adapter only 2 inches long, with a highly stable
and accurate 4-20mA output
MIST22 is a general purpose sensor
constructed with leads. Of simplest construction, it is the most
commonly used sensor in numerous types of applications. Standard
wire leads available are PVC, Teflon, Teflon with armor and Teflon
with stainless steel overbraid. Armored leads provide superior
mechanical protection. Fittings are optional and two basic types are
available: fixed and adjustable compression. Fixed fittings are tig
welded to the sheath. Adjustable fittings utilize a two piece
tapperd ferrule consturction and are one-time adjustable. Standard
threads available are NPT, but for larger volume OEM applications,
other thread types are also available. MIST22, in the temperature
range of -50 to 200 deg C, utilizes a thin film Pt100 RTD element
and in the temperature range of -200 to 600 deg C it utilizes a wire
wound Pt100 RTD element.
MIST22 does not require a separate
transmitter housing and installation is just the connection of the
two leads to the electronic system. This greatly reduces the
intallation costs. As well, MIST22 is more compact and can be
installed on equipment where small size is important and access
difficult. One further advantage of the MIST22 is that the
electronics are heremetically sealed and contained within the
sensor. In applications where moisture is a problem with
conventional field transmitter assemblies, MIST22 offers a perfect
solution.
MIST22 comes factory scalled and calibrated to
customer specified temperature range. No costly field calibration is
required. But if the customer ordered the MIST with the wrong
temperature range, or if the application changes, the MIST can be
re-scaled ot any range within the sensor limits. No re-calibration
using temperature baths is necessary. MIST keeps its accuracy.
Reprogramming is accomplished with an interface module and custom
software configured with a PC.
