    INTRODUCTION NOSHOK 204 & 304 Series Intelligent Sanitary Transmitters are solid-state pressure and level transmitters silicone sensor with a very high burst pressure. The sensor using a piezoresistive element is mounted in a Stainless Steel foot. Inside the foot a temperature sensor is also mounted to provide active temperature compensation at the point of measurement, to minimize temperature and position error.

    REMAINING 3.1 DIGITAL LOCAL INDICATOR NOSHOK 204 & 304 Series transmitters are standard equipped with a digital display. As standard transmitters are delivered with closed covers The three push buttons and the display are behind the cover (1).

  • Page 5: Push Buttons Functions

    PUSH BUTTONS FUNCTIONS The NOSHOK 204 & 304 Series Transmitters can be programmed easily by use of the 3 front panel pushbuttons. The display can show engineering units of inH O, mH O, bar and PSI. The functions of the three pushbuttons will be explained below.

    4.1 PROGRAMMING POINTS (P101 – P114) Programming points The following points can be adjusted with the three P101 Zero adjustment (4 mA) push buttons. For an explanation of these points see the following pages of this manual. P102 Span adjustment (20 mA) P103 Cancel mounting position effect To change one of these points you have to push on...

    CANCEL MOUNTING POSITION EFFECT P103 All transmitters are calibrated vertically. When NOSHOK 204 & 304 Series Transmitters are installed horizontally, there will be a small "mounting effect" on the zero (4 mA). For example, the transmitter shows 4.03 mA instead of 4.00 mA. This can be easily canceled with P103. In P103 there are three options: Nothing will be changed.

  • Page 8: P104 Pressure Unit On Display

    Canceling mounting position effect. (confirm with PROG). When SET is selected the transmitter is automatically adjusted at 4.00 mA. The span will not be affected. Do not apply pressure while executing "cancel mounting position effect" ADJUSTMENT PRESSURE UNIT ON DISPLAY (See Conversion table) P104 Several engineering units can be shown on the display by using a conversion factor.

  • Page 9: P106 Damping Adjustment

    ADJUSTMENT DAMPING (0 till 25 sec) P106 In P106 an electronic damping can be adjusted between 0 and 25 seconds. This can be done with the push buttons [↑] (up) and [↓] (down). Always confirm by pushing once at [PROG]. INDICATION OF PROCESS TEMPERATURE (READ OUT ON DISPLAY) P107 Push [PROG] until "100"...

  • Page 10: P111 Linearization

    The display will readout 'Curr' Confirm with [PROG]. The display shows '4.00'. Push [PROG] and the output changes to 4.00 mA. By pushing [↑] / SPAN or [↓] / ZERO, you can change the value on the display. The output value will change as soon as the [↑] / SPAN OR [↓] / ZERO button is released. Pressing the [PROG]-button again will exit the simulation.
  • Page 11 Enter the length (L) of the tank. For a "ball" or cone shaped tank, take the cylindrical length plus the length of 1 "ball" cone. (Confirm with [PROG]) Enter H3 in meters if the transmitter is installed like in the left picture. Enter 0m when the transmitter is installed like in the right picture.

  • Page 12: P112 Specific Density

    P112. When this option is used, the actual height of the tank must be entered. WRITE PROTECTION P113 The NOSHOK 204 & 304 Series Transmitters with HART-Protocol can be protected for adjustment (Write Protection). This is possible for two kinds of adjustments: Local changes with pushbuttons and display (Lo.Pr = Local Protection).

  • Page 13: P114 Response Time From Push Buttons

    The response time from the push buttons can be adjusted from 0.0 till 5.0 seconds. P115 & P116: SERVICE MENU Only available for manufacturer.
