YSI 071
Designed for long-term immersion at considerable depth, this style has a stainless/
neoprene vulcanized seal with a molded external splice protector. This assembly
method provides a high-integrity seal as well as mechanical protection to the
leads and the thermistor. For best long-term performance we recommend
glass-encapsulated thermistors (YSI 45000, 46000, 55000 Series).
Application: It’s designed for deepwater immersion and is frequently used to
measure the temperature of deepwater reservoirs, wetlands, and wells. Multiple-
year immersion at 2,000 feet is feasible. Several such installations are in place for
thermal gradient power generation tests. The YSI 071 can withstand the forces
of pier mounting in high-wave environments.
Typical Time Constant: 5 seconds
Temperature Range: 60°C max
YSI 081
YSI 082
The construction of these probes provides fast response and minimal stem effect
error when used with relatively lightweight and properly mounted leads. The
thermistor is electrically isolated from the case. These probes are not waterproof.
noncontact surface from high levels of radiant energy. This can be accomplished
by placing a reflective surface between the sensor and the source.
Application: Designed for permanent or temporary fixed-mount surface temperature
applications. Also for measuring coil and radiator temperatures in heat exchangers.
Typical Time Constant: 1.1 seconds
Temperature Range: Thermistor and cable dependent
Typical Time Constant: 0.3 seconds
Temperature Range: Thermistor and cable dependent
YSI 083 – 085
The 083 – 085 series surface probes allow attachment to a surface by use of screw
and are differentiated by mounting hole size and housing geometry. The 083 style
has the most rugged housing and offers the greatest surface contact. The 084 and
085 styles offer #8 and #6 screw openings, respectively. The 085 style allows offset
attachment due to its’ flag lug configuration. All flat surface sensors require good
surface contact while protecting the non-contact surface from high levels of radiant
energy. This can be accomplished by the use of thermal compound between the
surface and probe, and by placing a reflective surface between the sensor and any
radiant energy source.
Application: Designed for bolt-in-place applications. Used to measure, compensate
and control temperatures of motors, surface plates, heat exchangers, and fluid
pumping systems.
