GENERAL BULB INFORMATION
All bulbs are made of 304 stainless steel; capillary material is either copper or 316 stainless steel, as shown in the range table. The maximum pressure of bulbs
with a process connection is 300 psi. Other bulbs are for non-pressurized (e.g., open tank) use only. Consult the factory for higher pressure applications.
RANGE TABLE – NO. 2 BULB
Standard 11/16˝ Diameter Series D Bulb & 3/4˝ NPT Connection
RANGE TABLE – NO. 1 BULB
11/16˝ Diameter Series D Bulb for Open Tank Use
(1) All bulbs, including those with a copper capillary, are made or Type 304 Stainless Steel
(2) Insertion depth may be increased through use of bulb supports or wells. Repeatability: ±1% of full scale.
ݗ 1/4 HP at 120V AC, 1/2 HP at 240V AC.
ݘ DC rated controls (up to 10A), consult factory.

CAUTIONS
Control movement must not be oiled.
Do not overload – note electrical rating on nameplate and be sure total current
passing through switch is within specified rating.
WARNING: A failure resulting in injury or damage may be caused by over-pres-
sures, excessive vibration or pressure pulsation, excessive temperature, corro-
sion of pressure containing parts and movement assembly, electrical overload,
or other misuse. Do not tamper with switch wires. Position of these wires is
essential to proper operation. Tampering with these wires will void warranty.

Well Pressure Ratings
(1) All bulbs, including those with a copper capillary are made of Type 304 Stainless Steel
NOTES:
Dim. “E” = MINIMUM INSERTION DEPTH
Minimum clearance distance for bulb insertion: measured from the top outside
surface of female NPT.
Dim. “B” = ACTIVE BULB LENGTH
Length of bulb that responds to temperature change: measured from the free
end. Process fluid must have good contact with the bulb over this length.
