Catalog excerpts

Pressure Sensors Models: > SP96 SPC98 Introduction > Sitron's Pressure Sensors SP96 and SPC98 provide cost effective, reliable and accurate level and pressure measurement. These sensors are suitable for absolute pressure as well as for positive and negative gauge pressure. Like all of Sitron's products, the Pressure Sensors can be made in a wide variety of process connections. They feature easy installation (mounted at the bottom of a vessel), within a compact design. They also feature excellent repeatability, high accuracy, and maintenance-free reliability under varying environmental conditions. Technology > As the volume of the medium increases within a tank or well, the process pressure is applied to a 316 S.S. piezoresistive diaphragm cell (SP96) or a ceramic cell (SPC98). The external force of the process pressure creates a displaced electrical charge, which accumulates on opposing surface of the cell. In both cases this generate an output signal, which is converted to a standardized 4-20-mA (2 wire) signal that is directly proportional to the pressure applied. Features > Low CostRugged and compact design- Body entirely 316 S.S. Loop powered Absolute and gauge pressure ranges Temperature compensation Ceramic sensors for SPC98 models High accuracy Excellent repeatability approved size="-2">

The SP96 pressure sensor is made with 316S.S. piezoresistive cells filled with silicone or oil. It is design to be installed at the bottom of the tank. The SP96 pressure sensor is offered in 316 S.S. with a 4-20mA output signal, as well as a great variety of pressure ranges and connections. The SP96 pressure sensor can also be offered with a Zero and Span adjustment. The SP96 models can be easily customized to handle a wide range of applications for different types of liquids, a variety of food industry applications, as well as for gases. There are advantages (such as wide frequency and...

The SPC98 dry and flush mounted ceramic pressure sensor uses an aluminum oxide ceramic sensor as a "dry cell" that is extremely resistant to overload, aggressive mediums, extreme min/max temperature, applications with solid particles and low pressure ranges. It is designed to be installed at the bottom of the tank. As opposed to the 316S.S. piezoresistive cells filled with oil, the process pressure actsdirectly on the ceramic diaphragm. The actual measuring range of the sensor is determined by the thickness of the ceramic diaphragm, which if overloaded, stops on the ceramic substrate...

Sitron's Hydrostatic Level Probes have identical features as the Pressure Sensors with one main difference: They are submersible. Hydrostatic Level Probes are specifically designed for depth/level measurements in groundwater, deep wells, water towers, rivers, sewage treatment plants and other similar applications. The Hydrostatic Level Probes are fully encapsulated and are housed in a weatherproof cylindrical enclosure. Offering a great degree of flexibility, they can be constructed with 316S.S. rigid rods or with special cables for depth measurements. These probes can be made with either...

The HL842 is designed for short measurements with a fixed 316S.S. rigid rod. There is no pre-set limit for rigid rod lengths, but the longer the rod gets, the more difficult it is to transport and install. Sitron recommends lengths no greater than 8 feet (2.43 m); for lengths greater than 8 feet (2.43 m) the HLC842, having no pre-set limit on cable lengths, is the ideal solution. The HLF842 has an electronic module in the probe's enclosure with a Zero/Span adjustment.The HLF842 submersible pressure sensor uses a 316S.S. piezoresistive diaphragm filled with silicon to interface between the...

The HLC842 is the ideal solution for depth measurements, but it works as well for short measurement applications. Like the HLF842, the HLC842 also has a 316S.S. piezoresistive diaphragm filled with silicon. The advantage of the HLC842 is that the special polyurethane waterproof cable, which connects the sensor to the monitoring device, permits unlimited length for depth measurements. The HLC842 has an electronic module in the probe's enclosure with a Zero/Span adjustment.Pressure ranges from 0 to 29PSI (0 to 2bar) gauge. > DIMENSIONSWIRING DIAGRAM 3 ݔ (89mm) Connection diretcly to the power...

The HL840 is exactly the same as the HLC842, with only one difference: The electronic module is located inside the capsule along with the sensing element. The HL840 does not have an enclosed housing or process connection. It is only the sensor located at the bottom of the cable.Pressure ranges from 0 to 2900-PSI (0to 200 bar) gauge.Sitron's HL840 has been successfully applied in the field to depths of 2000 ft. (610 m). > The HLF842C is designed for short measurements with a ceramic cell and rigid rod. It has the same features as the HLF842, but this one is made with a ceramic cell. Sitron...
