Senasys Capillary Switch Series Other Capillary Switch Series Capillary Switch Description
351 Series or 358 Series A19 Series Remote Bulb Control by Johnson Controls These temperature controls  are available with SPST switches that open high or open low. Models are also available with SPDT switches that can be wired for open high or open low applications. The controls are
available with fixed (factory set) or adjustable (screw or knob). Various control ranges are available to cover working
temperatures from 0°F-700°F.Features
• Constant differential throughout the entire range
• Compact enclosure
• Variety of sensing element styles
• Unaffected by cross-ambient conditions
• Auto or Manual Reset
351 Series PECO T103, T125 Electromechanical component thermostat available in adjustable and fixed setting models. SPDT switching capability up to 25 Amps. Bulb and capillary sensor is available with optional fittings and finishes.
351 Series Honeywell Remote Temperature Controllers, Series: T4031, T6031, L480 For limit or temperature control where remote mounting of sensing element is required. These temperature controls are SPST or SPDT, manual or auto reset.

Features
• Liquid-filled  elements provide rapid sensing to control the system.
• Control temperature in a duct, tank, freezer or cooler (0°F-700°F).
• Controller element can be directly immersed in the controlled medium.
• Adjustable or fixed control setpoint.
• Ambient temperature compensation provides good temperature control.

351 Series Selco CAP Series, The CAP and CAP-MR series are commercial and domestic electric thermostats for heating and cooling applications. These 20 amp snap acting switches are SPST or SPDT available in auto reset. The remote bulb and capillary are available in copper or stainless steel in lengths up to 13 feet. They are used in a variety of liquid or air applications as a regulating control, high limit or trip free device. Many models available from stock or built to your specification. Selco’s hot capillary thermostats.
351 Series Langir Electric – WK Series Elements: The volume of the material in the temperature sensing part of temperature controller will expand or contract when the temperature of the controlled object varies, which causes the film box that is connected to the temperature sensing component, which drives the switch on or off through a leverage function to keep a constant temperature. WK Series Liquid Inflated Temperature Controller is characterized by accurate temperature control, reliable, small on/off temperatures difference, a wide range of temperature control and large over loaded current etc.

351 Series EGO Products Single-Pole Thermostats EGO single-pole thermostats and limiters. With a design designed to maximize flexibility, the EGO single-pole thermostats and safety temperature limiters can be supplied for any application requiring electrical circuitry. The designs differ mainly in the following features:
352 Series Honeywell Remote Temperature Controllers L482 / Selco / Tempco / Robertshaw / Whitman Controls / Barksdale Senasys offers the addition of a second switch, which opens the range of applications for a capillary thermostat, 352 series. The two switches can be any combination of a single pole, double throw (SPDT) automatic reset; or a single pole, single throw (SPST) manual reset. The 352 series differential can be factory set very close for a double pole application or widened out for multistage applications.
352 Series EGO Products Multi-Pole Thermostats EGO multipolar thermostats and limiters.
With a design designed to maximize flexibility, the EGO Multipole Thermostats and Safety Temperature Limiters can be supplied for any application requiring up to four electrical circuits or more electrical power. The designs differ mainly in the following features:
354 Series PECO L117, L107 Electromechanical component thermostat available in fixed setting models.

SPST manual reset switching capability up to 30 Amps in addition to SPDT switching capability up to 25 Amps. Bulb and capillary sensor is available with optional fittings and finishes. Sensor has “negative bias” construction that provides for switch open upon bulb or capillary rupture.

354 Series  Selco CAP-MR Series The CAP and CAP-MR series are commercial and domestic electric thermostats for heating and cooling applications.
