Gems Sensors Series Level Transmitters
Small Size – Alloys, Compact Analog Sensors
Quick Specs...
- Stainless or Brass Construction
- 1/4-inch Resolution
- Lengths to 144 in (366 cm)
- OEM Configurations Available
- Analog Output
Overview / Design Principle:
These compact transmitters feature the rugged durability of stainless steel or brass construction. The XM-800 series provides analog output, and can be combined with Gems Digital Bargraph Display and Level Cube Receivers described in this catalog.
Completely electronic, Gems Liquid Level Transmitters provide reliable and durable remote tank gauging. A wide variety of material combinations provide compatibility for most small to mid-size tanks in both process and OEM applications; for deeper tanks (to 18 feet) look to Gems 36000 and 66000 Series.
Gems experienced engineering and sales staff can provide customized solutions for applications not satisfied by the standard transmitters shown in this catalog. Do not hesiatate to contact Gems if you require a configuration not shown here.

Switch actuation levels are determined following the guidelines:

Overall Length = Inches of Indication + C + X
|
|
C
|
Distance From Bottom of Mounting to Float Stop (Customer Specified)
-1/4 " (6.4mm) Minimum
-1-1/4" (31.8mm) Minimum on Type 1, XT Series only.
|
|
Calculating LengthTo find Overall Length when Inches of Indication is known: Inches of Indication + C* + X = Overall Length
|
|
To find Maximum Inches of Indication when Overall Length is known: Overall Length - C* - X = Maximum Inches of Indication
|
|
*C dimension is determined by customer
