800 Series Indicating Temperature Switch

 

For applications that require a visual display of process temperature and set point, the 800 Series offers a highly readable four inch setting/indication scale. It is available in two versions: a Lexan® enclosure for enclosure type 1 or 4 applications (with option M300), and with Lexan® window and epoxy-coated aluminum enclosure for Div. 1 explosion proof applications. For temperature indication only, the T800 thermometer incorporates the same performance and construction features of the 800 Series.

Specifications:

 

Storage Temperature                 -65 to 160°F (-54 to 71°C)

 

Ambient Temperature                -40 to 160°F (-40 to 71°C); set point typically shifts less than 1% of range for

   Limits                                          a 50°F (28°C) ambient temperature change

 

Set point                                     ± 1% of adjustable range

   Repeatability

 

Shock                                          Set point repeats after 15 G, 10 millisecond duration

 

Vibration                                      Set point repeats after 2.5 G, 5-500 Hz

 

Enclosure                                    Types 800, 802: Lexan® black finish; clear Lexan® faceplate

                                                        Types T800, 820E, 822E: Die cast aluminum, epoxy coated enclosure,

                                                         gasketed; Lexan® cover andfaceplate

 

 

Enclosure Classification            Types 800, 802, T800: Designed to meet enclosure type 1 requirements (enclosure

                                                         type 4 by specifying option M300). Types 820E, 822E: Designed to meet enclosure

                                                         type 4X; Class I Div. 1products meet enclosure type 7; Class II, Div. 1 products

Switch Output                              One or two SPDT; dual switch may be separated up to 100% of range; except type

                                                         822E where switch #2 can be set up to 25% of range span below switch #1 set

                                                         point. Switches may be wired “normally open” or “normally closed.” NOT

                                                         APPLICABLE TYPE T800.

 

Dual Switch Adjustment              Type 802: Dual switch controls have separate knob & temperature pointers for

                                                         each switch set point (standard); turn inner green knob for setting #1 switch; outer

                                                         black knob for switch #2. Type 822E common adjustment single knob and pointer

                                                         for set point

 

 

Electrical Rating                          15 A 125/250/480 VAC resistive. Electrical switches have limited DC capabilities.
