UCL-200 Premier Continuous
Ultrasonic Sensors
Accuracy of ±0.25%
Easy push-button calibration
Automatic temperature compensation over entire range
Filtration eliminates false echo signals
Small beam (8°) allows installation in tight spaces
Our premier ultrasonic sensors are available in three models:
Intrinsically Safe (201001): This two-wire model provides non-contact
measurement up to 18 feet. Approved for use in Class I, Groups A, B,
C and D; Class II, Groups E, F and G; Class III; T3C environments, the
transmitter is an excellent choice for use with solvent, hydrocarbon and
petroleum type liquids.
General Purpose with Relays (201002): This three-wire model provides
non-contact measurement up to 24.5 feet and features an integral relay
for pump, valve or alarm control. This transmitter is an excellent choice
for applications with dirty, coating, scaling or corrosive type liquids such
as wastewater, crude oil or wax.
Long Range with Relays (201003): This flange mounted, three-wire
model provides non-contact measurement up to 40 feet. Its deeper
measuring range makes this general purpose transmitter ideal for large
bulk storage tanks, water or chemical reservoirs and waste stations.
Media examples include chemicals, acids and slurries.

The exceptionally
compact, almost
“wafer-thin”
design of GEMS 65800 Series zener barriers saves
space and simplifies installation. They limit D.C.
voltage and current to the hazardous area and provide
a path for fault current. Encapsulated construction is
impervious to dust and moisture.
