SOLID STATE RELAYS
MORE FOR LESS: LONGER HEATER LIFE AT LOWER COST
Watlow solid state relays (SSR) offer many of the advantages of solid state power controllers, but at a lower cost. Watlow’s extensive knowledge in power controller design led to the development of a special fast cycle input card that enables a solid state relay to operate from a standard 4-20mA instrumentation command signal. Test results show that zero-cross solid state relays in combination with the fast cycle card promote better temperature control and longer heater life than slow cycle relays. Through a time proportional cycle rate of 1⁄10 of a second, heater life will be extended.
Both low and high voltage solid state relays are available from 24 to 660VAC. All ac output models include back-to-back silicon controlled rectifiers (SCRs) for a more rugged design than the traditional triac-based solid state relay. The internal design allows it to tolerate high currents and harsh electrical environments of heavy industry. Watlow also offers a switched VDC model for dc heating applications.
Watlow provides all of the components necessary for trouble-free operation. This includes two standard convenience items: a thermal foil to ensure proper thermal transfer from the relay to the heat sink and belleville washers to ensure that the relay is mounted with sufficient pressure to enable good heat transfer. Matched semiconductor fuses and heat sinks are available to complete the power switching package.

THERMISTORS
FAST, ACCURATE, REPEATABLE TEMPERATURE MEASUREMENT
Watlow thermistors are designed to ensure fast, accurate and repeatable temperature measurement. Thermistors are highly sensitive to small changes in temperature and maintain accurate temperatures over a limited range. These sensors are made with either epoxy-coated or glass-coated constructions and can be used in the most demanding environmental conditions.
- Designed to maintain accuracy over the life of the sensor improves process control
- High resistance reduces the chance for errors
- Interchangeable maintains good system repeatability
- Point sensitive senses temperature in a very specific location
-
TRUE SURFACE THERMOCOUPLES – STYLE TST
INCREASE SURFACE TEMPERATURE ACCURACY WITH IMPROVED THERMOCOUPLE DESIGN
Watlow’s TRUE SURFACE thermocouple (TST) offers superior accuracy for measuring flat surface temperatures. This compact, highly accurate sensor isolates the thermocouple junction from ambient airflow. The TST typically achieves accuracy and repeatability between one to two percent (ΔT).
The TST, with its removable molded cover, fits into corners and other tight locations. TSTs are easy to install with a variety of commonly used screw types.
Watlow’s TST sensor is ideal for many applications including semiconductor chambers, platens, packaging, cleaning and food preparation.

WATROD AND FIREBAR ANSI FLANGE IMMERSION HEATERS
AGENCY CERTIFIED TUBULAR HEATERS IDEAL FOR HEATING LIQUIDS, GASES, TANKS AND PRESSURE VESSELS REQUIRING HIGHER KILOWATTS
Watlow flanged immersion heaters are easy to install and maintain. Designed for heating liquids and gases in tanks and pressure vessels, flanged immersion heaters are ideal for applications requiring higher kilowatts.
Watlow flanged immersion heaters are made with WATROD or FIREBAR tubular elements brazed or welded to a flange. Stock flange heaters are equipped with a general purpose terminal enclosure.
Flanged immersion heaters, with FIREBAR elements, also answer the need for liquid immersion applications requiring high kilowatts in small tanks. The FIREBAR element’s unique flat surface geometry packs more power in a smaller bundle, with lower watt density, making it especially well-suited for petroleum-based liquid heating applications.
- UL® and CSA component recognition
- ANSI and ANSI compatible 2, 2½, 3 thru 48 inch flanges
- All units are inspected and/or tested to ensure element-to-flange pressure seals do not leak
- Integrel thermowells provide convenient temperature sensor insertion and replacement without draining the fluid being heated
- Standard, general purpose terminal enclosure for easy access to wiring
-
WATROD™ AND FIREBAR® SCREW PLUG IMMERSION HEATERS
IDEAL FOR DIRECT IMMERSION HEATING OF LIQUIDS
Screw plug immersion heaters are ideal for direct immersion heating of liquids, including all types of oils and heat transfer solutions.
Available in a variety of sizes, Watlow screw plug immersion heaters feature both WATROD round and FIREBAR flat tubular elements.
Heating elements are hairpin bent and either welded or brazed into the screw plug, depending on element sheath and plug material compatibility.
General purpose terminal enclosures are standard with optional moisture resistant, explosion resistant and explosion/moisture resistant enclosures available to meet specific application needs.
Optional thermostats provide convenient process temperature regulation to the screw plug immersion heater.

WATROD™ ENCLOSURE HEATERS
PREVENT FREEZING AND CONDENSATION IN ELECTRICAL AND MECHANICAL HOUSINGS
WATROD enclosure heaters are designed to prevent freezing and condensation in electrical and mechanical housings. The WATROD heater element is enclosed in a perforated, aluminized-steel bracket to prevent direct contact with the heating element.
The enclosure heater’s stainless steel sheath wall resists corrosion and protects the heating coil from exposure while the silicone resin seal provides protection against humid storage conditions and is effective up to 390°F (200°C).

WATROD™ TUBULAR HEATERS
FITS VIRTUALLY ENTIRE RANGE OF IMMERSION AND AIR HEATING APPLICATIONS
Available in single- or double-ended termination styles, the versatile and economical WATROD tubular heating element from Watlow lends itself to virtually the entire range of immersion and air heating applications.
The single-ended WATROD tubular heater design has both terminals at one end. The opposite end is sealed. Flexible lead wires are 12 in. (305 mm) crimp connected to the terminal pin and have silicone-impregnated fiberglass oversleeves.
The double-ended WATROD, with its round cross-sectional geometry, are highly adaptable for bending—especially when bending is performed in the field. Watlow’s double-ended MULTICOIL tubular elements offer various combinations of resistor coils and thermocouples inside one sheath. They have the ability to sense the heater’s internal temperature accurately every time, or offer three-phase capability in one element.
Both single- and double-ended WATRODs share many construction features delivering long life—the resistance wire is centered in the heater sheath and electrically insulated with compacted, high-grade magnesium oxide for superior heating performance.
WATROD tubular heating elements have a variety of mounting and termination options making them highly popular among industrial customers.
