| Specifications: | |
| Stem Lengths: | 2 1/2", 4", 6", 9", 12", 15", 18" and 24" (available up to 120") |
| Stem Diameter: |
.250" standard up to 42" stem. .375" standard over 42" stem. |
| Connection: | 1/2" NPT. |
| External Reset: | Easy to calibrate by inserting 1/16" Allen wrench into reset opening. |
| Construction: |
304 stainless steel external parts. Welded construction. Corrosion resistant to most chemicals. |
| Hermetic seal: | Per ASME B40.3 dustproof and leakproof. |
| Harness: |
All stainless steel brackets with screws that loosen
to allow 360° rotation of head and 180° adjustment of stem position. |
| Bellows: |
Heavy-duty flexible stainless steel. Hermetically
sealed at case and connection. Protects mechanism that transfers temperature change from bimetal coil to pointer. |
| Dial: |
True Anti-Parallax dial, easy-to-read from any
angle, minimizes reading errors. Anodized aluminum with large black numbers and graduations. |
| Lens: | Glass. |
| Bimetal Coil: |
Helix coil is silicone coated on ranges below 500°F
for vibration dampening and to maximize heat transfer and response time. |
| Accuracy: |
+/-1% full span per ASME B40.3 Grade A. Adjustment
of the angle between case and stem may affect accuracy up to 0.5% of span (ASME B40.3). |
| Over Temperature Limits: | Up to 250°F 100%; 250°F to 550°F, 50%;
550°F to 1000°F, continuous use up to 800°F, intermittent use over 800°F. |
