Sensit – Pressure OEM Series PA

“The Standard”  OEM Pressure Transmitter 4-20mA Output.

The PA-Advanced series is a two wire, 4-20mA pressure
transmitter and is available in standard ranges from
0.5 bar to 600 bar, or may be scaled to customer
requirements. All ranges are available in gauge or
absolute format.

Description:
The PA-Advanced pressure transmitter is based on a four active arm strain gauge bridge fused to a high purity
alumina ceramic diaphragm, offering high natural
output coupled with superb chemical and corrosion
resistance. This is housed within a stainless steel case with integral electronics and is supplied with a plug and socket electrical connection. Pressure connection is a G1/4 male thread as standard. Other threads are available on request.

AECO-Capacitive Level

Capacitive level sensor for bulk products   SC and SCD series:

These are used where it is necessary to control with a high degree of security the level of non conductive substances both liquid and solid.

They are particularly used for controlling the level in silos for cereals and foodstuffs, in feed plants, foundries and cement works.

They function in the vicinity of the material to be controlled:

  • Supply voltage 24 Vac or 110/220 Vac
  • Relay output with 1 pole changeover from 5A to 220 Vac.
  • Led incorporated
  • Sensitivity adjustment
  • Selector of min/max level
  • SC series with power supply-amplifier incorporated within probe
  • SCD series with power supply-amplifier separated from probe
  • SX2 type with power supply-amplifier in plastic body
  • Bar electrodes of teflon in standard lengths of 300/500/800 mm
  • Plastified cable electrodes in standard lengths of 1/2/3/4
  • metres
  • Housing in aluminium alloy with threaded fitting 1.1/2 inch GAS

Sitron-Pressure Transmitter with Local Indication

Sitron`s STD-P Pressure Transmitter is designed for both pressure and level measurement of liquids and gases (air) for temperatures between -20C to +80C.

This unit features an integrated digital display (which can be rotated 332º) enabling the user to monitor the signal output at the site of the process, ideal for applications with difficult access or where you need constant follow-up. The innovative mechanical assembly also rotates, making it possible to adjust the positioning of the electrical connection and display window separately. With local push buttons on the face of the housing, set-up and calibration of the alarm points as well as configuration of the digital damping can easily be performed.

The STD-P is offered with either a 316 stainless steel or ceramic sensing element, which provides a linear output signal 4 … 20mA (2 wires) or 1 … 5Vdc (optional). Transmitters are custom produced, with various types of connections, and factory calibrated measuring ranges from -1 to 200bar (relative or absolute pressure).

FEATURES:

  • Simply to Calibrate
  • 2 Programmable Alarms
  • Easy to Read Digital Indicator
  • Precision Mounting with 360º Rotation of the Display and Electrical Connection
  • Digital Damping 0 … 20s
  • HART Communication Protocol (Optional)
