Thermometrics range of Self-Adhering Surface
Temperature Sensors are designed for industrial
HVACR applications, typically for placement
on the external wall of a water tank or boiler
reservoirs. They are also suitable for reservoir
tanks working in conjunction with solar panel
water heating systems. This range of adhesive pad
sensors detect over-temperature resulting from a
malfunction or a dry-fire.
Pressure sensitive adhesive tapes loaded
with ceramic powders provide high thermal
conductivity and thus excellent heat transfer
from the heat source to a NTC thermistor while
maintaining appropriate levels of dielectric
strength. An adhesive lined foam backing tape
provides air and moisture resistance with optional
WRC (5470) water safety and DIN 4102 part 1 (B3)
fire safety approvals.
Features
• Excellent heat transfer
• Long-term stability
• Multiple adhesive tape sizes and shapes
available
• Various lengths
• Temperature ranges from -30 to +70 °C.
• PVC single insulated lead wire, 3x1.5mm cross-
sectional profile.
• Voltage withstand: 750 Vac between the
terminals of the connector and the contact
tape, for a broadly sinusoidal wave form at 50
Hz, where the max permissible current is 1 mA.

Product Applications
Placement on Water Heater Tank
The sensors are designed to work in predominantly dry
environments and are particularly suited for domestic
applications where they can be positioned between
the water tank and an insulating jacket as shown. The
sensors should NOT be used externally where they can
be subjected to wind, rain and direct sun.
Residual oil on the surface of a metallic tank, resulting
from a drawing process, can cause a loss of adhesion.
Oil residuals should be cleaned away before the
application of the sensor.
