MOUNTING AND PROCESS CONNECTIONS OPERATION MANUAL

1. MOUNTING AND PROCESS CONNECTIONS

The MST2000 can be mounted in any di rec tion. There may be a mi nor ef fect on Zero
that can be cor rected by the setup pa ram e ters.

1.1 MST2100: NEMA 1 En clo sure

A. Re view the di men sional draw ing on page 5.
B. Pro cess con nec tions are via 1/8" NPT fe male ports lo cated on the bot tom of the hous ing. The high

pres sure port is la beled “HIGH”, the Low pres sure port is la beled “LOW” on the mount ing plate.

1.2 MST2400: NEMA 4X En clo sure

A. Re view the di men sional draw ing on page 5.
B. With out a con tin u ous purge op tion, pro cess air should be non-corrosive and dry. If a con tin u ous

purge op tion is in stalled please re view sec tion 2 on the con tin u ous purge. The con tin u ous purge
must be bal anced.

C. Pro cess con nec tions are via 1/4" NPT fe male ports lo cated on the bot tom of the en clo sure. The high

pres sure port is la beled “HIGH”, the Low pres sure port is la beled “LOW”.

1.3 Three Valve Man i fold

A. It is rec om mended that a three valve man i fold be in stalled in the pro cess, un less a con tin u ous

purge is in stalled . A three valve man i fold is avail able from the fac tory. It is in stalled in the pro cess

lines to iso late the pro cess sig nal dur ing in stal la tion and/or re moval of the MST2000 thus pre vent ing
pos si ble trans ducer over-pressurization and to zero trans mit ter.

þ Notes:

& Be fore con nec tions are made blow out pro cess lines throughly.
& It is rec om mended that pipe thread tapes not be used on pneu matic pip ing.
& Soap test all joints and fit tings for leaks.
& Pro cess lines should be the same di am e ter and ap prox i mately the same length.

þ Note: MST2000 DP sen -

sor max i mum op er at ing
static pres sure is 25
PSID.

2. CONTINUOUS PURGE OPTION

The MST2400 can be or dered with a Con tin u ous
Purge Op tion. This op tion sup plies a con tin u ous
pneu matic purge to a Thermo Brandt pitot flow
sen sor to keep the sens ing ports free from plug ­ging dur ing op er a tion. There are Purge Bal ance
ad just ments lo cated on the front panel which
pro vide for the ze ro ing of pro cess air re sis tance.
If the Con tin u ous Purge Op tion has been or ­dered, please read the fol low ing setup in struc ­tions. The Con tin u ous Purge Op tion must be

bal anced once the pro cess is con nected to
the MST2400.

A 1/4" NPT fe male air sup ply port is pro vided on
the bot tom of the en clo sure for the Purge.

An in ter nal fil ter is sup plied with the unit, but air
sup ply should also be fil tered and reg u lated.

þ PROCESS LINE LENGTH & SIZE

& When a con tin u ous purge op tion is used, the pro cess

lines (Hi and Low lines) must be the same di am e ter
(pref er a bly 3/8" or larger) and the length of each line
should be the same within +/- 5%.

þ IMPORTANT:

& The Con tin u ous purge op tion air sup ply should be only clean, in stru ment qual ity air and should be greater than 20

psi (1.4 bar) and not ex ceed 100 psi (6.9 bar). A pre-filter should be in stalled in the sup ply line if the air qual ity is
sus pect. A 5 mi cron fil ter and a 0.3 mi cron co ales cent fil ter are rec om mended. Fail ure to pro vide clean, in stru ment
qual ity air through the Con tin u ous Purge can cause the MST2000 to give er ratic read ings. Fail ures at trib uted to a
con tam i nated air sup ply are not cov ered un der the war ranty.

C. The in te gral fil ter will turn “RED” as it cleans the air. Re place the fil ter be fore the “RED” reaches the

right side, or out let end.

3. In te gral “High Pres sure” Blowdown Sys tem

The MST2400 can be or dered with an In te gral “High Pres sure” Blowdown Sys tem. This op tion is de ­signed to clean out Pitot Av er aging Flow sen sors us ing a blast of “High Pres sure” Air (up to 100 PSIG or

6.9 bar) while hold ing the last out put sig nal from the MST2400.
The MST2400 is ca pa ble of be ing pro grammed to per form a blowdown se quence any where from ev e ry

2 min utes up to once ev ery 24 hours (1440 min utes). The blowdown se quence can also be ac ti vated by
a re mote pulse from a DCS or other con trol ler.

A. Spec i fi ca tions:

a. Air Sup ply: Max i mum of 100 PSIG (6.9 bar) . If air sup ply is over 100 PSIG then a reg u la tor must be

in stalled.
b. Volt age: 120 VAC. Op tion con tains in te gral 24VDC power sup ply.
c. Se quence Du ra tion: Approximately 30 sec onds from time sig nal is held till sig nal is re stored.
d. Tem per a ture: Max i mum 150oF.
e. Pro gram ma ble intervals: 2 min utes to 1440 min utes (24 hours).

f. Pulse Sig nal from ex ter nal controller: Con tact clo sure for ½ sec ond (500 mil li sec onds).

B. Se quence of Op er a tion

a. The MST2400 be gins the Blowdown se quence by hold ing the last out put sig nal. “-HOLD-” will ap -

pear on the LCD. The Blowdown Status In di ca tor will also be lit. See the sec tion on the LCD Dis play.
b. Valves are ac ti vated to iso late and vent the trans mit ter from the pro cess to pre vent dam a ge.
c. The Hi & Low pro cess lines are al ter nately blown down for ap prox i mately 11 sec onds each.
d. Valves are au to mat i cally ac ti vated to re store sig nal from pro cess back to MST2400.

C. Ex ter nal Ac ti va tion Sig nal

The MST2400 In te gral Blowdown can be ac ti vated by a ½ sec ond ex ter nal contact closure pulse sig ­nal. The Blowdown can be con trolled by this sig nal only or in com bi na tion with the in te gral con trol of the
MST2400. The MST2000 must be pro grammed to ac cept this sig nal. Re fer to Pro gramming Pa ram e ­ters, Sec tion 8. See Wiring Di a grams in Sec tion 14.

þ Note: A 110VAC power source is re quired for the In te gral Blowdown Sys tem. An internal 24VDC
